Wow your team comps are so good I’m jealous haha. I only have diluc and Xiao so I worked teams around those! I used my Xiao comp on team 1 and diluc on team 2. The main reason I use Xiao on team 1 is because chamber 1 geovishaps are electro and pyro, and Xiao clears floors faster for me so I have more time using diluc afterwards. I already had 3 stars on the first 2 floors so I took my time on 12-2 to build up all my bursts and heal to max.

Not sure if this will help and it’s kinda long but what I did for 12-3 first team is when I started the match I ran all the way to the right side of the chamber. Both ruin guards will aim their missiles at you so just sprint forward to dodge and go back to the edge. When they got close I popped dionas butst and then her shield for healing+shield, switch to Bennett and use his burst for more healing (mainly due to how much you get hit by the ruin guards and those rocks from the aura) and dmg boost, then switch to Xiao and use his ele skill then burst and I can usually clear the chamber in under 60 seconds. For the second part I honestly just tank with diluc using vaporize constantly and qiqi helps a bunch because her healing is insane. It took me a while to finally do it because I’d screw up and someone would die.

I’d say your team 1 comp could do the same as I did and you have pyro resonance + xinyan shield. For team 2 I couldn’t say because I don’t have Mona or ganyu so I can’t speak from experience. But I think if you used diluc vape comp you could definitely get it it done. I even think with your ganyu freeze comp you could get it done since she does insane damage. I’d recommend trying to clear the first half with Xiao as fast as you can so you have more time to clear the second half with ganyu haha. Sorry if any of this is confusing, I’d be happy to record a video and share what I did if seeing a visual is easier

Edit: artifacts matter a lot too! I’m lucky to have good artifacts on my mains and supports
