I really hope the twitter pedo shit doesn't like just completely taint Klee's reputation. She's a really funny character conceptually, pretty much the equivalent of if Ralph Wiggum learned how to make bombs. Maybe not the exact same kind of bumbling innocence as Ralph, but there's definitely a similar kind of energy to her.
There's no other explosion based character aside from Klee as far as I know. It'd be kinda cool if they made a character with a similar playstyle that lobbed ice chunks that exploded into shards or something instead of shooting exploding fire lasers. It's fun as hell when you manage just go and stun lock and juggle enemies with just a series of well placed lasers and bombs, and I've never really gotten that same controlled chaos kinda experience from other characters I've unlocked. Everyone else is like "uhh shoot arrow?,stab? spinny thing? thing launches and hits a few enemies with a little homing attack maybe?" Meanwhile Klee's just like over there killing everything including herself with her own moves. Not because of some health bar drain stipulation like other characters, but because the grass and everything else is covered in hellfire and explosions. Definitely not as efficient as some character movesets, but a lot more fun gameplay wise for me.
Despite having quite a few characters unlocked, my party keeps pretty much having to default to "NOT LINK", Klee, Qiqi, and Fischl. Considering you NEED an archer and healer to a degree options are limited as hell, and the combo I've got set up seems to be the most efficient setup for elemental reaction damage bonuses. Sending a horde of enemies off to their deaths in inescapable flaming tornados is the best shit to watch. When you line up the shot right they just drop fucking dead.
