If she takes regular baths, i could live with everything else :P
As for Beatrix in Four Kings, eh i guess when facts are laid down, you can say that having her there isn't smart, however in new game, her being there doesn't make any difference whatsoever. In my first two new games in this game, i summoned Beatrix to Four Kings as i had no idea she would raise their HP but it didn't make them hard, i was still hacking them down fast.
However summoning her in new game+ and onwards, you might want to pass.
While we're beating dead horses, MLK thinks I'm bad at PvE because I said you can literally beat NG with just about anything because it's not hard after you've played it a while. And then he misconstrues it as a personal attack on his NG+7 abilities and that I'd bring an un-upgraded broken sword or something at level 1 into the Manus fight or something on NG+7 (which is the only thing he talks about or can relate to). And he also summons Beatrice for 4 Kings.
I think he's just that bad and is projecting that onto others. So, I will additionally confirm that MLK is a bad player. I mean, you'd have to be to summon Beatrice for 4 Kings and think it's helping you.
It sounds like you and MLK are having trouble in the bedroom. --- I use Gamefaqs as a toilet to crap out as much hate and venom as possible so I can be happy and nice in everything else I do. sorry Gamefaqs =/
in my experience she gets in the way and messes up my roll timing on the moonlight butterfly's heavy attack. with four kings she provides an occasional distraction for more free hits and flask windows, if a second king does spawn she'll keep it off you and if she does add more hp i didn't notice it fighting them.
