Pandora isnt too fast in my opinion. for incite/pacify to work there has to be targets, usually sorrows, and sometimes enemies. they have to all succeed, and in succeeding against your friendlies you are messing up your activation order so your opponent can know where/when to strike, which i think is a reasonable cost for the speed. And she will still get outrun by fast models if she has unlucky draws.
I think she is a pretty tough cookie to crack. Ive played 3 games with her, havent lost so far, but havent won either. My biggest problem is making a crew for her that will accomplish my scenario goals. Treasure hunting, holding ground, recon, sorrows are useless at them all, and the other guys cost too much.
My opponents would probably tell you pandoras toughness is equalled out by her so easy to kill crew. They also lack a lot, in that most of the spells who whole crew puts out have effects that last until the end closing phase, rather than until the end of the models next activation. It makes a lot of them pointless if that model has already moved this turn, and this go's to the whole crew.
The other thing to remember is that self loathing isnt that good of a damaging spell. always has a negative flip, and it depends on your targets own melee weapons.
Then again maybe im playing her wrong, maybes i should just be aiming to make my opponent lose a lot of morale duels instead of trying to kill them.
