Well, I can't speak for anyone else but I've never really cared much for Alisae either.

I didn't get the impression from Arenvald that he was overly confident or arrogant, though. He specifically has a somber moment where he reflects on not being as strong or special as a lot of other combatants. That aside, the last time he showed up in the story as a major focus was back in 4.1, which is quite some time ago now. Alisae and G'raha have been given far more focus since that point which I'd wager contributes to why they're starting to wear thin/overstay their welcome for some.
