1) Horrible clunky transformation. Maybe this is just a PS3 thing, but transforming into a vampire lord is slow and clunky. Press R2.... nothing happens for a few seconds. Then it goes through an animation during which you can be attacked but do nothing. And when you want to revert back to normal form it's the same slow process, except your character just suddenly pops back to its usual form. It just feels so unfinished.
2) Why can I open doors in vampire lord form but not loot anything? Did the devs not realise how much of a pain it is to have to go through the tortuous process of reverting/transforming just to loot stuff? Sometimes I can't even be bothered to loot because the transformation is just too slow.
