Let's see .. I'm no expert with this kind of thing but im gonna give it a try ..

The only reason i think why 3rd Raikage is Stronger than the 4th Raikage is, because of 3rd's Passive .. 3rd Ay gets more Atk/Nin and Def for each extra chakra you have, so making a team with one chakra feeder can make 3rd Ay a beast .. or even without a chakra feeder ninja, as long as you have extra chakra, he will get extra additional buffs .. Not to mention if you put all high-leveled equipment, runes and magatamas with him and also the buffs from his team like Darui's Barrier and Lightning Main's Passives ..

While on the other hand, 4th Raikage c*so deal massive amount of damage, but and it has a but, but you need to make him powerful enough to deliver great number of damage .. Without proper equipment and items loaded to his arms, this Raikage will fail to win battle ..

When it comes to Standard Attacks and Mystery Skill, 3rd Raikage is the winner again, he can do a Standard Attack that can make damage also to the other ninjas in line and his Mystery Skill can damage all ninjas in the line where his target is .. Unlike 4th Raikage, he's prone to Clone-Decoys, once he tagged a Clone, he will attack it again and possibly start a combo that is useless ..

That's the only thing i can think with your question, let's wait for other users to share their thoughts and opinions about the Raikage Family ..

(EDIT : Oops! I didn't see the "in the arena" part .. anyways, still close with your question, hope i helped you even a bit)

Short answer: Depends on the team you are using.

Longer answer: Both kage's SRs are underpowered and outscaled by most of the newer rares and event ninjas. That's why they perform so poorly.

To refer to the subject - Ay 4th is way better imo. Why? I use Ay4th, Samui, Darui and LM in arena, and:

1. Im still able to get 6 paths rank

2. Can 1shot a ninja in 1st round with combo (when vs immunes, can get lucky)

3. Ay4th is 1st rounder, need to keep Ay3rd clean until round 2, and with LM 1st mystery I easily beat Ay3rd.

So, where is the problem? Well:

In case of both Ay, Han owns you, Masked Man owns you, dont wanna talk about Shisuis and Minatos Anyway, they are great for LM teams, unfortunately, LM lives his hardest times atm, so they both cant really shine...

u c*e

Samui ay3rd *x

Wind main ay4th *x

summon:dog of hell

wind main dance of impetus.shadow clone .combo blade of wind,flower guard multi shadow clone.

even if u encounter masked man he can only stop the 4th ay

you will eat your words when he get skill books i promise you that

4th raikage will be a super beast after he got his skill books :). Super damage with mystery every rounds, immunity every round (from his mystery), defense from chakra scaling . He will be one man army, check the youtube video bro. He is a good investment for sure :).

After that, kakuzu earth grudge online will begin lol

idk, i use third ay as my main team on my server. and the only that can really beat me as the few p2w players that have 20k more power. but around my power and maybe 5-10k more power then me usually dont beat me.

he is useless , his skillbooks must costed 300frags you can figure how much is that. only to get interrupt by iruka. cant even bother to make him

u clearly dont understand what feature will come to us in the future

Iruka?

I don't even think he would be pos 1 to stop Ay.

Even if Iruka is actually pos 1. He won't stop Ay, with experience players they would already know how to counter.

Masked Man is the real problem to Ay.

True. Thats so true. But, i have hopes that in some close future there will be cheaper Katsuyu breakthrough gems, so u can upgrade it to heal AND clean debuffs, and problem solved.

Well, think about it when Ay 4th gets skillbooks he will still get immobilized (and debuffed) by Masked Man just as easily, and if you are playing Wind Main with Reset Coodown you can immobilize him the next round as well OR, you can play Fire Main who at that point can immobilize immune & pure immune ninjas.

That being said Fire Main with modified mystery + Shisui + Masked Man and let's say Jonin Minato with bonds mystery = no problem.

Unless it owns 7k+ control than enemy masked man. Who does use masked man as move 1?

Hmm, you realize Ay 4th Mystery gives more standard attacks, it's not prompt, you wait for him to do it and immobilize after, removing his immunity and buffs.

u clearly dont understand about it. Do u think an expert player will use lightning main? no, they will use earth main double attack mystery to cleanse the debuff. Even if u use fire main immobile mystery, it wont do much damage to 4th raikage team. In round 2 or 3, u will be a dead meat lol. Not to mention there is Samui and Yamato anbu for interrupt/immobile lol. 4th Rakage defense and damage will be heavy buff with chakra lol, and he can do mystery every round lol

just accept the defeat of ur team hk minato iruka kurenai wind main

Lol trust me, when he comes, Masked Man + Fire Main + Jonin Minato + Shisui/Iruka will be too much for him.

Masked Man will immobile him and remove Samui's buff + Earth Main's buff, Fire Main will have genjutsu mirror + immobile mystery and an experienced player will never get interrupted.

Jonin Minato can round 1 cause paralysis, so no more combos for that team too. Shisui will round 2 chaos (barrier bonus is nice too), or Iruka will be there for buff/shields and it's still more than enough to defeat that team.

I also forgot to say that at that point sleep will be more widely used than that AOE fire standard.

Ehm, lets say he goes with MB + samui + darui.

He just waits to see what happens in round 1, hoping samui or darui (almost granted) start a combo if ay doesn't directly start it on your main.

At that point you are in his hands.

Beware that minato is almost for sure in front of ay so doesn't get the cd reduction in round 1.

Uhm... you can still 3hit combo with standard attack and trigger Jonin Minato's Mystery cooldown reduction.

And that team is literally counter to any Ay 4rth Raikage team with all the skillbreakthroughs in the world, he is just bad vs CC. And that one does a hefty amount of damage too.

At that point of game when his skill books are out that team doesn't really stand a chance as Garv said.

By that time Earth main would use Chakra wall r 1 and have Katsuyu can remove immobile debuff.

A roughly 4k cps for Katsuyu stones vs Ay skill books.

I bet Katsuyu would be at max mystery before his books are out, thus a p2w i know already has katsuyu maxed.
