I think it's insane that you guys are defending Poe and this meta. Was it balanced before? No. Is it balanced now? No. How are RNG matches enjoyable to you guys? What is fun about starting a match and having 2 of your characters die before taking an action?
Sure, if RNG falls on your side you will be able to win against a strong Poe team, but your matches shouldn't be luck based.
There are a lot of characters who don't show their strength until turns 3+ but in this meta you can't even use them because battles don't last long enough to. I would say that Poe would be less viable if the overall pacing of a battle was slowed down so that everything wasn't killed before taking action but that's not the current state of the game.
So to balance that the devs need to either make a drastic change to the entire pacing of Arena or a band-aid approach to the underlying issue and nerf Poe/FOTP/etc.
Also, the dumb AI actually makes it easier for offensive Arena matches. If this was true PvP I can guarantee you that a P2P Poe team would have the highest win rate in the game right now.
