Well before it left, I went back into the 2nd challenge of the potions event and did a proper run with a good score. The frustrating thing about the event is that they expect your first run to kinda suck and then you have to go back and do it for real for the higher end rewards. The thing is, it's not compelling or interesting enough to do more than once for most people, so nobody wants to do it for a pisser of a reward like 3 xp books or 20k mora. It's extremely important to plan out a route with your strongest team having the hardest enemy layouts, and even then you can't judge the layout properly just from the screen that shows which enemies will spawn. For instance I took Venti into one of the ones that had a bunch of small hilichurls shown, thinking i'd use the succ to gather them and then explode them with Electro Charged Childe. He ended up being useless though because they only spawn 2 at a time instead of all at once, which ruined the advantage of his elemental burst. That was my 3rd encounter out of 4, so when I hit that, I got a shit score and it ruined the whole run.
Anyways, long way to say that I'll be giving the event a bad score on the survey. I like the idea of battle events that you can use trial characters and your own characters, but the flow of this one was just shit. I did get all the rewards finally though other than those ore for the 18k score. My heart broke when I got 17,983 on the one and I said "fuck you game".
Windtrace, man they really expect us to grind this out. I feel that 3.5 minutes per match is just too long if we need to get >3000 coins for the whole event. This would be a great mode to add in to play just for fun, but I don't like being forced to grind it for rewards.
*edit*
We got skeleton data for the upcoming new characters:
This means Yelan is the tall woman model, Heizou is the teen male character (Benny/Razor/Chongus sized), Kuki is teen girl (Fischl, Xiangling), and Ayato is tall male (Zhongli, Diluc).
