While that is good, there is still obvious flaws that really ought to be ironed out.
So, you talked about how they wanted Unity Leaders to have better AI....
Let's talk about Apururu (UC) a little.
She's a very nice healer... she's got Nott, she's got Martyr, Devotion, and Convert. I don't think I've seen any other healer (who is a WHM) last anywhere near as long as she can at later levels, unless you bite off more than you can chew. She uses Curagas were most won't, and she's usually the fastest to remove bad status effects.
However... there are a few things she does that is very annoying.
First off, her incessant Stoneskin spam. While she's quick to status cure, a lot of times she'll be caught in the middle of a Stoneskin cast and of course, you're there losing HP, or what-not waiting on her to finish casting Stoneskin. And the sad part of it is, she rarely gets hit and when she does, her Stoneskin ain't going to save her much MP anyways. She uses more MP on Stoneskin than she would use just curing any splash damage she takes.
There's the subject about convert... how about make it she only casts Stoneskin when she gets to <25% of her MP (to prepare for an upcoming Convert)?
And also, her insistence upon running around everywhere... she drags GEO trusts around with her, oftentimes putting you outside of their buffs if you don't call your NPCs out in the right order, and if she pulls hate, what you're fighting goes running over to her, potentially causing more links and aggro while you try to deal with the situation and then she'll keep running around in random directions making things worse while you're trying to get the thing back because she decided to dump a Cure VI on you at the very beginning of the battle, literally after the first swing. Then she starts running around, dragging the mob (and you) all over the place, rounding up MORE links and aggro, and she keeps pulling hate because then she keeps spamming cures on herself and you, and it just goes down hill.
So... if she has hate, she should STAY PUT and don't move.
