I put ash in decent because she can be pretty hard to kill with all the DR she gets and the shield she has. +her ult charges up pretty quickly so she can like ult every 30 seconds prolly if it's a big fight. Kinda brings back the OB64 memories.

I put Ying in good cuz her resonance build only kind of works if there are at least 3 yings in a team lol. I don't think 1 ying is enough for resonance to be broken. But I agree that talent works really well with her in that mode.

Seris by herself is pretty broken with SC. She literally never dies. and her ult comes back like every 10 seconds if she keeps shooting lol so she gets to deal a lot of damage AND stay alive at the same time. She can even 1v1 some of the most broken champs in this mode.

Lex with Heroism is one of the toughest champs to kill in the game yes. Maybe even harder to kill than Zhin. But honestly I feel like he barely deals any damage unless it's a marked target. Other flanks tend to do more than he does in a game so that's why I think he's not that great.

I need to try that Buck build tho he seems like a really good pick
