i think its great how most SK choose to ignore our unique abilities... reaver is like a solid 300hp tick. you do realize it procs off about every one of our ability right? even taunts and mana tap. add in the aoe heal and the extra heals on tap viens from the 300hp heal from every mob it hits and you will be making the heal parse (which = you surviving longer). i have not noticed much difference in the new %, but i would never dream of dropping this spell.
and pools of blood is meant to be a safety buffer for healers. its an extra 3k hp just incase you do hit below 0. if your healers are letting you eat dirt that long.... maybe time to check yo heals :P many times a group of double attack spike dmg has come in and that extra 3k was enough to survive attacks that ive seen guards die on. if you have good healers you should never be in that below 0 zone for more then maybe 0.5 - 1 sec.
and someone else said it, you can get all 3 end ability. short a few points from rescue, cause if you cant hold with a normal rescue, the bonus wont help much... neither will that 3% hate transfer :P build your groups right and pull a hate building toon in.
one day i hope sk stop thinking they are a dps class, realize we are tank/utility, and stop giving the real SKs a bad name
