If you get all 6 of her chases off, it combines to about half the damage of tobi's single chase ;P

It is more based off how difficult it is to obtain a ninja, than how good it actually is. Quite a few of the "top tier" ninjas (like ay and minato) are expensive collector's ninja that has no viability when trying to compete.

Honest, you should separate inside arena and outside of arena. The way arena "equalize" stats significantly benefit some ninjas while notably nerf others.

Examples of arena changes:

Self stacking ninjas like roshi, kimimaro, sailor sakura are far squishier in arena than outside, due to lack of hp mood.

Heals have 50% power (instead of 100%) if you do not have healing tips, further reducing the tankiness of ninjas like s sakura and roshi. With healing tips from water main, heals are at 90% power instead of 140% power.

base stats and stat growth of ninjas matter a lot more; a 5k attack standard really hurts against 2.5k defense and 10k hp. A 12k attack vs 9.5k defense and 17k hp does not hurt nearly as much. Against a blitz team who win barrier, breeze dancer (who has garbage def growth) dies in 3 standards in arena. In an 80k vs 80k fight outside of arena, she can survive all 4 standards + chases.

Defense/resistance modifiers like tag, and kage minato/hiruzen passive make a bigger impact in arena thanks to the non-linear damage formula.

-------

Kage minato's skill set get huge benefits in arena, making him perform far better there than outside of arena. He is relatively speaking, far harder hitting, and more tanky when compared to a sage or matsuri fight against an equal power opponent.

--------------------

Second issue: certain ninja combos work extremely well at stomping weaker players quickly, and falls flat against someone slightly stronger; while some ninja combos are relatively consistent.

The black hidan, roshi, bee team for example is crazy good at stomping players just 10k pow weaker than you; cripping them in round 1 and finishing it off round 2 with no contest. The damage output drops off rapidly at equal power, and becomes very subpar against someone just 10k power stronger.

The han, roshi, sailor sakura team does not really change in kill speed regardless if your opponent is 20k stronger or weaker than you.

Kage minato also suffer from this issue outside of arena: he is so dam good at 1 shotting teams 20k weaker than you at start of round 2; yet he get wrecked by most f2p meta teams 10k stronger than you.

--------------------

PS: This team is fun :)

Personal experience. A lot of the arena stuff comes from testing things against myself using 2 accounts; then using the same team against each other outside of arena.

For the hidan roshi bee team; if your opponent is 10k higher power than you, the team just won't do enough damage to kill anything on round 1. If you don't have initiative advantage, your roshi is very likely to get sniped at start of round 2, while hidan end up low hp or dead to splash and self inflicted damage. putting yourself in a very bad position against any of the common f2p meta teams. Danzo over bee makes the team function well against any f2p meta team, at expense of being extremely vulnerable to healspams. If your opponent is 10k weaker than you; your roshi is safe from snipes and likely faster, allowing you to just finish off the opponent at start of round 2.

Regarding kage minato outside of arena, I'll admit, I'm biased against him from personal experience. I regularly face Hidan, roshi, bee, mb teams; roshi, han, ssakura, water teams; s itachi, masked man, fire, danzo/onoki teams. All 3 of these teams happen to be bad matchups for minato.

Sadly he retreated before I could * him up.. already popped his dodges at this point.
