2. I have been keeping up on leaks and it looks like Inazuma is going to have stupid amounts of free primos floating around, but don't get too sucked in by the newer units being released. My guess right now is that Baal will be as broken as Venti/Zhongli so I would make sure to have enough to pull for her if you care about good units more than hot bitches at all.
electro support, and going how past archons are handled I fully expect it to break the game in some way or another, especially if it goes bonkers with dendro. who knows, it might even make lisa viable (as if).
for now it's not out yet if she'll show up in 1.7 (which will probably have the first part of inazuma, else they'd have to do another area to farm drops for kazuha and other inazuma chars released in 1.7) or to spearhead 1.8 which drops in september right for the first anniversary. there's rumors they want to go all out for that but that might just be wishful thinking.
I wouldn't count on ayaka, yoimiya etc to show up anytime soon, their announcements were mostly to fuck with leakers, and there is still dendro coming which will most likely have it's own free char + banner companion (probably yaoyao and baizhou, and given the money the klee banner made dendro loli will probably be the 5*).
shit's gonna be busy, yo.
I just hope the devs update the game to make world exploration more interesting again. Pretty much every treasure chest in the endgame is pointless besides the primos you gain. Money and upgrade materials are pretty easy to grind.
It would also be pretty nice if the game had enemy material grinding points where you can fight shitload of enemies from specific types. Like Abyss Wizards.
that's not limited to chests, 9/10 rolls are literally trash weapon exp you'll find more of just stepping outside. same as your double compensation, you get
one extra roll if you have already maxed that char, and since 9/10 rolls are shit it's a complete waste.
drops are easy to farm tho, I think now the book even jumps to the next target automatically (and with the cicin mages there are even more than it will list, so if you know those spawns you can get even more daily).
