Spoiler: 
try caledor then...generaly i dont know exactly but ratio of drop is near 1/10 - this is why number of mobs that you can kill in short period is so important ... and this is why riposte/self heal wh or sl is way ahead of wp in butchering department. wp is only better in champions farm and scavenging realy
Spoiler: 
btw mate your SM is squishy as hell but as a glass cannon you at least have dmg burst Just remove gusting wind from your rotation it gives only immunites
and wp.... when ppl see your wp and no other healer in pug pt, they very often crash their game. didnt you notice that;P
