I have take improoved VE. Ok, it must heal me for 67% of my shadow dmg, but combat log and archud says that it heal me only for 25%^^. Guys pls check it on ur chars. I'm rly interested it's only my bug or may be someone have a same problem. Or may be someone know how to fix it. thx 4 your attention.
just as a detail. VE was 25% heal from dmg pre lk, but after lk arived it was modified so only the priest gains 25% and others get 5%. This was changed because sp was a too good healer since it's dps was increased. so the base talent now gives 15% selfheal 3% group heal, the iVE gives 33%/67% heal increase. Anf finally blizz tryes to all talents in the same way so no more questions are rising. Like talents giving 100% bonus dmg on critical spell, hits and everyone(not everyone) thought you will add 100% to the existing 150%, instead it was the critical bonus of 50%(from normal hit) increased by 100% that meaning you will add a 100%(from normal hit) to a normal hit dmg... => your crit will be 200% of normal dmg.
it was 15% for all the group (including you) before the patch 3.0.1
they nerfed it because, with all our new dmg buffs... this is a shit load of free healing :P
now if you have imp VE... you heal yourself with 25% of your dmg and 5% for the group. this is very strong, when my VE is up, i can stay in aoe or use my pw: death and heal myself very fast. this is a very strong self heal. one of our best tool.
