So for the weapons: It's better not to go for the Fontaine weapons. For Gaming, you're better off Earth Shaker, a Natlan craftable weapon that you could get for free(not sure if you still can from that certain event). It makes Skill hit harder when a Pyro related reaction is triggered, and plunge from ult and ability are both ability damage. As for Lynette, you're much better of going with Iron Sting. Swirl dmg scales with EM, so it means with VV Lynette can do a bit more personal dmg. It can also be passed down to Kuki for Hyperbloom team.
I appreciate you doing the trials with the restrictions. That's how I do it on my swords account. So there are trials I've skipped completely because there were no sword characters. At least all the trials will always have some four stars.
Sadly not all 5 star trials have 4 stars I'm pretty sure that on one of hutaos reruns she was the only character in the trial and I think that happened with some other character
1:18 my favourite region to explore is definitely mondstat. there is a reason it is my only 100% explored in game. its just so calm, easy puzles, and a nostalgic feeling for some reason.
My fav 4 star is Faruzan. I got her as I was pulling for wanderer and she was only meant to be the support but I really fell in love with her animation when she uses her skill or burst and also her voicelines
About the Gaming cons, they are definitively worth it. If you manage to get him c6, you got yourself a broken pyro dps. Like legit, c6 Gaming can do thousands of dmg no problem. Even without Xianyun or Furina he'll be fine. C4 is also a good thing to have if you already don't, as you won't need to worry about getting ER in his artefacts, just atk and crits. Rosaria is also good to have if you happen to get her from the banner as well. If you get Sucrose and Bennet in the future, then with her+Gaming you got yourself a comfy melt team. Edit: Okay so you got Bennet. Congrats uwu. I'd say that Bennet could replace Layla and Layla could go to the Dendro team. Layla doesn't spam Cryo that much to interrupt the dendro reactions, so she can go there. And Gaming will certainly appreciate Benny's buffs and the two Pyro resonance Yet another edit: Beidou is like a hybrid. She can be a main dps or a sub dps. She's a really good electro applicator and she gives interruption resistance when her burst is used. If you ever get Sethos, he'll like Beidou on the team(Aggrivate Sethos would be with Beidou/Yaoyao/Collei and Hyperbloom(if he likes that reaction) Beidou/Xingqiu/Yaoyao). However unlike Fischl or Kuki, Beidou is not that good for hyperbloom as the electro trigger. She's much better suited for overload or taser teams.
Anwsering your question about the abyss. I liked it more when it was half a month. Because then I could get primo's every half month and we get less primo's form the abyss now. Which will be not to much with the new endgame content. But still 400 primo's less then we used to. Just wanted to comment this.
i'm playing my own version of 4 Stars only - but even more basic. My game is : no wishing (apart from Noelle). No levelling up after ascending at L40. It definitely makes the game more casual without the primogem angst and no endless grinding for character levelling material.
