Do all ya'll still just predominantly just rock 1 team?
I switch out my teams fairly regularly. I may not do uber mega damage (my highest damage was just something over 50K using Mona's alt combo with someone else and got the achievement for it; I normally average between 10-30K max tho), but it keeps the game fresher for me to keep switching out squads. Plus, I have them catered for situational efficiency and effectiveness. I have more fun this way.
My go to team right now is Eula, Zhongli, Fischl, and Bennett. Prior to that it was Hu Tao, Venti, Xingqui, and Diona.
Occasionally I work in Childe, Sucrose, Chongyun, Diluc or Razor. I just leveled Kazuha so once I finish his artifacts I'll add him in somewhere too. Albedo too, at some point.
My highest damage is around 500k with Eula but all that crazy damage shyt doesn't matter, as long as you're having fun. I think the most HP an enemy has ever had in the game is 2 million and it was that Legend Of The Vagabond Sword event, with the +175% HP option on for more points. Which you didn't even need.
Literally nothing in the game needs the damage these characters can currently put out....nowhere near it, actually. So 50k is not bad, at all.
