there's 1 point i agree with you, need to have more skill trials ninjas, it's fun and experimenting and also useful... BUT the rate they are releasing the skill trial, for me, it has to be slow, because if we got too many skill trials too quickly, the game will be broken and p2f cant play because they cant keep up.

on the other hand, try some skillbroken ninjas, you may like it...

For example itachi fully broken is so so good, when u put him as a tank (well not too great if he has too low hp), he could dodge standards, chases AND mysteries endless times when his barrier is on (which is prompt when +2, too op), if he doesnt dodge, and suffers debuffs, he'll transfer ALL debuffs of him to the other team...and if u pair him with han, it's like having madara5kage and more (clear buffs + destroy barrier + tank + dodge + debuffs transfer)

and for your information, fu breakthrough puppet passive +2 is awesome in arena, because water sharkbomb cant kill it with her mys (even when crit i think), thus make her chaos, ruining all combos...

skill broken kurenai is god tier support ninjas, so i wont talk about her, and so is fully broken gaara
skill broken lee pair with skillborken yamato is good for 9tails, and pvp too if u got higher ini than your opponent (in pvp try onoki then yamato, since he has auto barrier)

skill broken hanzo is good too, imagine the opponent suffering 8k dmg from poison at round TWO...

and while u r in arena, try skill broken deidara, his mys +1 in round 3 deals like 3k dmg to ignited ninjas... u cant rarely get a 3k damage in arena that fast xD

So try something for fun,use your creativity haha.

please dont say it's useless unless u try it...

i have 130k bp, and i'm currently using han-itachi right now (that's why i suggested it haha), water main (sharkbomb spam), han, itachi, kurenai... and i can beat 170k, 180k and even 210k with higher ini than me... even i cant imagine how does that weird-hearing lineup works, but i tried anyway because itachi's my idol... and out of my surprise, it works in sage as well as mats and in some cases, a surprise team in space-time where every debuffs comes for itachi and he reflects them all...

For hanzo and fu, agree that Y is better than just +1 or +2, but keep in mind that when u break him to +2, u can switch to AND back with Y+1... hanzo frags is not cheap though, i'll give u that (well i dont have him yet lol), but fu frags can be farm... and idk if u aim for edo hashi or itachi ssn... if u aim for itachi, u should have fu 4 star with like 120 or more frags when u have itachi, and u can buy fu's frag by survival points too...

For yamato and lee... yamato is only good in 9tails, and idk if he's better than hashirama... but he's p2f friendly, whild hashiirama needs rng luck, and lee is really good in mats when u have enough support (usually iruka, earthmain, kurenai/onoki if u r tanky enough) and the lower his hp get, well u know what i mean :)

speaking of RNG luck... rmb that experimental vials is RNG base... so if u got Y+1 skill alr, and u forgot to lock it, or u dont have experimental protection vial, that may change back to normal skill, and the amout of tries u have to do if unknown, so u may spend 100k moon to get the skill set u want... and yes those vials r easy to obtain... but why spend 20k moon for vials and protection when u c*e that for 100 keys or 50 medium refine runes... to be honest, a 200k team 7 (normal naruto, sasuke and sakura with all fully breakthrough + fire/water main) can defeat a 100k team with some awesome ninjas, and u know those 3 r the easiest to get, right?

so if u r f2p, please focus on power and farm stuff, and be creative and fun with the game xD.

well for the record, i have my itachi 5-star-ed with 400 frags before they release his breakthrough, so i still have those 2 books hahaha

and never say it's not pratical when you are actually using it, please

if u say that vials r more pratical, try having the frustration of keep refreshing skill again and again and again for like 50 vials, and u have wasted 10k moon...

well i'm not talking about the rare breakthrough ninjas, because for the price of their frags, 200 sun is kidda worth it (advance vials will be sold at a price of 200 sun), but be patient, u'll save money for power and a lot of things when u r patient, grinding frags is free afterall. xD

i'm not saying skill experimenting is bad, i'm just saying it's not worth investing on those low-price ninjas..., and while u wait for oasis to release them, use anything u got...

have u considered ay4 skill trial?
and we already have yamato anbu... so yeah...

please read all my sentences. i told that guy at my very first sentence: "there's 1 point i agree with you, need to have more skill trials ninjas, it's fun and experimenting and also useful... BUT the rate they are releasing the skill trial, for me, it has to be slow, because if we got too many skill trials too quickly, the game will be broken and p2f cant play because they cant keep up..."

i just pointed out that the way he/she thinks about breakthrough skills are useless is wrong =_=, and it's proven by many people... thanks to all of u guys btw (heart emotes)

true that experiments is useful, but I dont know when they'll release them, and so do u. So while we wait, just try to breakthrough some ninjas, u'll be surprise. Honestly.
