idea/alternative for undeath passive

CordingOnyx

So i think that most folks (pve and pvp) can both agree that undeath at rank 1 isn't great, if anything its a buff if you compare it WITH the drawbacks and benefits of rank 1-3. so as an alternative what if they put the damage resist in a skill instead so rather than it being passive and always on, its a choice that has to be considered if you want to sacrifice a slot. I was thinking it could be something like a morph of blood frenzy (the one that slowly drains health) so that it is a toggle where it gives a damage resist the longer its on AND drains health so it has to be very conscious of when its on and whether or not you can actually sustain it. Maybe it could even go up in resistance given the higher your vamp rank ( maxed 30% at rank 4 vamp ) wanted to get some opinions in this!
