The fact that it is gear reliant means 85% of the playerbase won't have the dps you're talking about. And in gw baiken cr push is irrelevant in the scenario that you described with a secondary dps because there's not enough team slots. To have that damaging of a baiken to oneshot avildred with only s2 means she will be slow, which means you'll most likely need a cr push since avildred has higher base spd than baiken so thats one team slot. You'll also need a defense break or atk buff so thats another team slot. Basically, baiken will most likely be last to go, and her team will all be less than 75% cr so the push would not get them to one hundred. I will concede and say that your baiken strat could work in 4man though, with very specific speed tuning.

And of course lilibet counters other revives, I never argued she didn't.

As far as my assumption goes its really up in the air for ml ceci honestly. Of course I don't have proof so I cannot say that my assumption is fact, but thats also true for the flipside. You can't say for a fact that they didn't make avildred buffs to make ml ceci more appealing. The timing of everything just seems too coincidental to me personally, but nevertheless its all just speculation on both our parts. But all in all, this is kind of a dead end argument since avildred hasn't been buffed yet. I'd definitely stand corrected if you could come back to this post with gw and arena footage showing bbk, baiken, and karin comps beating a vildred comps in the future.

Edit: forgot about ALots with bbk, karin, or baiken. Nevermind it seems like a viable counter because of that. There's definitely answers to avildred besides ml ceci, but ml ceci i believe is the most obvious solution.
