lewds aside, the aspect of battle in Genshin Impact are good too.
Also Beidou is pretty nice in combat too.
The fact that each character ability is pretty unique is a double-edged sword. In one side, it makes battles interesting even if you swap one character from your 4-man rooster. In the other hand, lacking specific character means you're gonna be royally fucked on some situations. For example, anybody who doesn't have any non-pyro archer would be struggling really hard to do the 3rd level bounty Ruin Hunter that has Pyro immunity, but take increased crit damage and weak against weakspot hits.

Yeah. Hence you'll need to had a variety of characters that allows you to fight effectively.
