Tobei, what PvP actually matters? Cause as far as I'm concerned Space-Time doesn't matter cause it isn't real PvP, its just Ranked Battle with X-Server built in which is absolute garbage, so obviously the high P2W ninjas you claim are going to do well when a player has 0 control. Sorry that is AI vs AI not Player vs Player. Also

Real PvP is Arena, Bonds, GNW, Plunder, SWB, Matsuri

The server I play on has quite a few players who are 50k+ running Mei/Mabui/Tenten for real PvP. While I have bits and pieces of meta like teams because I have * luck. Then people wonder why I don't do any of the PvP events cause of crap like this and "immortal teams". (that and * matchmaking doesn't help) Hell I got to Special Jonin in arena just from running Sailor Sakura, Kimimaro, Kabuto, Water Main. But that is a whole different story.

But I'm going to break down this team for you. First, this team can beat players who are 10k-20k power higher than Mei/Mabui/Tenten/Water Main as long as they have initiative.

Mabui gives all Lightning/Water ninjas shields. So the line up is more tankier. She also gives 40 chakra round 1, then 80 chakra round 2. That is a bigger chakra advantage than running Itachi (Not susano'o). She uses her mystery to target a ninja to prevent them from doing anything, could be to stop a key chase, or even interrupt something because of Mei's chase. On top of this she can heal dispersing all Debuffs on the target. Which is something not even Sailor Sakura can do.

Then you have GNW Tenten while at 2 stars her damage/survivability isn't as good as a 3 star ninja, but because of the events she is in, or just pulling edo enough to 3 star her, changes that. She also increases your crit rate for 3 rounds by 15% which increases the damage output. Then she has a chase 10 which that team can easily go into, that paralyzes the targets of her chase. Then she has her mystery that she c*e Turn 1, the moment that Mabui gives 40 chakra, which her mystery is every chakra nature, so everything more or less is taking extra damage.

Then you have Mei, she provides a barrier that buffs attack and ninjutsu by 40% then before each of her actions once each round, she poisons 2 ninjas. She deals 25% extra damage to male ninjas. So that is lets say 65% boost in her damage alone plus the extra crit increase from GNW Tenten. She has acupuncture on her standard, then her chase inflicts immobile. Then her mystery inflicts aoe damage with ignite. She is undoubtedly the BEST Kage ninja in the game as she can basically do everything except heal obviously (unless for whatever reason you're a fire main using ninjutsu urge in which case sure)

Then you have the Water Main, whom uses Water Enhancement which buffs Water Ninjutsu/Attack by 40%, so now your Mei and Tenten have 105% damage increase and 80 respectively. Summons a clone to protect the Tenten which odds are will be shielded by Mabui to make it tankier that inflicts acupuncture. Then she performs the role of healing, having her healing standard being boosted by the ninjutsu buffs as well as healing tips, then runs her healing mystery to make sure everything is alive and has no debuffs on them to deal a lot of damage from mei in round 2, especially when they combine Mabui's mystery with the healing mystery to make sure to keep one of them cc'd.

This forces you to run a few things, A ninja with immobile (Or blitz the mabui down if you can), a manual barrier or a ninja that breaks barriers, Or ninjas whom are immune to debuffs.

And considering Oasis opens up an ungodly amount of new servers a week, you can't say that low power PvP does not matter because the moment that people start drawing in kage and are able to piece together this team, they'll essentially beat everyone not running those teams, unless they have a lot more power and more initiative. Especially if they are a spender running this team. So telling people that they have to essentially run crap like Kyubi Naruto or Hokage Minato with Sailor sakura, yeah good luck with that. There is no way in hell that I'm going to spend that much cash to get Kyubi Naruto to 3 or even 4 star (let alone to recruit it as Oasis hasn't shown me why I should bother spending, as most browser games are not worth it). Hokage Minato is also arguably the worst (by forums) Hokage.

(Also yes I know that isn't how percentages work, it just makes it easier to show it like that)

Doesn't always work, I seen some players move it into position 3, or even switch it up to prevent that.
