Which champ is the biggest pain to fight against in arenas?
I find the following to be more annoying than average, these are only a few things i can think of that can make arena annoying-
Unstoppable Colossus: everyones gonna fight one eventually and they seem hyper aggressive in arena and with unstoppable they can be quite a drawn out fight tho those who like to grind quickly. Just annoying and with the bleed immune ugh haha.
Hyperion: yuuup- power gain and often he will just not use his specials or bait out when fighting someone with higher atk, waiting for sp3 about 75% of the time IME unless you use a lower atk champ, seems to wanna draw the fight out.
Mordo: overly passive, but at the same time uses specials much more often than the average champ. Not too hard usually.
BPCW- stun immune can draw fight out longer than one would like.
Evade champs- Spidermen, BW, Ultrons, Nightcrawler. Self explanatory , usually np
Stunners- Ronan early on, Thor, Hulk, JF,Gambit
Shrugger/Decrease debuff- Kingpin, CB,AV,Karnak,Beast, Rogue
Shields- Modok and Medusa
Thornies/Unavoidable Dmg- Morningstar, Electro,Dormammu, Magik.Iceman,KM
Immunes- Iceman, Mephisto,Abom,Red Hulk
These apply to situations you may face, not necessarily every time and there are other things like bypass abil-acc.
Just wanted to share this.
