Not sure if it's all melee but Leina (wind melee) seems broken in PvP. A 50k one can beat my 70k Khalis because her regular combo ends with some kind of knockback and she attacks fast enough to lock her from doing anything. Since I can't control them in arena PvP, she's pretty much screwed in a 1v1 with her.

I recall someone saying Lv30 raid drops having 2.2x or something higher drop rate. Honestly, I see little difference between spamming Lv10's solo and Lv30's solo. Infact, I get more overall drops spamming 20 10s than 10 30s. If I'm lucky sometimes a Lv30 run will give me x2 of a weapon shard but that isn't often and doesn't make up for the overall recruitment orders spent to total drop rewards ratio. Until my units can auto battle it without any help, I honestly see no reason to even bother starting one as even clearing it takes more time. And I don't wait for other players if starting a run, it's already time consuming enough to use all 20 orders. Joining one might be okay since you don't use any recruit orders, that is if you still want to run raids.

Also, does anyone have any information on how events are handled in this game?
