The Vibro event was where Yae shined for sure. I don't know about you guys but she carried my teams across the finish line each time she was there.
I'm pretty sure the whales would have had their Ei's built up not to mention other good characters so the benefits of Yae were probably not important when they can cross the 2000 point line in seconds. But without investing anywhere near that much on my teams Yae was definitely a welcome team member. And mine is still lvl71 with lvl7 Talents because of my budgeting strategy. 
Even on the day that we had a Trial Ei the Archon did nothing. I think I finished that side with less than 900 points. I think she's better at tankier bigger enemies than mobs of small ones. Then it was up to Yae's side to pick up the slack and she did amazingly.
There's no downplaying the benefit of having her level of damage just firing away in the background. Sometimes when I'm just using up resin or doing Dailies I'll finish battles without even knowing it because those towers are killing stuff off screen lol
===============
But the thing I take away from this event most is that I got to try out Morgana for myself. 
It's not bad. Most of my points came from this side. Lag really hurts it though because you have to be able to keep up the rotation to do the most consistent damage and also to keep the permafreeze going. Otherwise you'll start taking damage and there's no healers on this team.
And because of that I actually have to disagree with TenTen. I think Kazuha would still be much better with Mona/Ganyu than just this Morgana team.
No matter what Venti's just not that good. Sure his black hole lasts long and can suck up enemies. But if they don't get sucked up the thing is basically useless. This is unlike Kazuha who sucks anything up with his skill and follows it up with 200%ATK Plunge damage and his Burst that pretty much does the same thing as Sucrose's. And combined with Freeze the plunge also adds shatter damage. On Kazuha day I noticed I was clearing out more stuff than with Morgana. On top of that you don't need Diona or Rosaria. I was using Barbara because of the Corrosion thing in the level and I was still doing more damage than Morgana. Slap on Yae and Kokomi for the other side and this was my highest scoring day.
Finally this was my first time checking out the Geo Allstar Team. That was fun. So much Geo energy flying around to power up Itto. You have Zhongli's invincible shield so don't even worry about damage. And then double support on Itto's Burst with Albedo and Gorou. This team wrecked everything! It almost makes me want to get Albedo since that's the only one I'm missing on my own roster. Also my second highest scoring day.
What about you guys? For my fellow f2p/casuals who was your MVP? And for the dolphins/whales what was your high score and how easy was it for you?
