you cant compare logs that easily unless you use same healers (and number) , fight is same length (time) and you follow same raid healing cd rotation. You seem to have use traquility early so i guess your group knows about it . You used 3 traq in 7:39 meaning you cast one traquility to top soakers ,i guess, other groups choose to heal through and use it abit later that does't mean he is doing something wrong . Also thalus did 2.176.839 damage while you did non. His uptime on spells is also better but if i can read logs correctly you used more rejuv possible blanket the raid since its 10man while he used less rejuv but more wild growths and swiftmend combo i guess. Both of you did quite well in that fight so be proud of it :P
Concerning fon the 7 casts / 290k per minute is based on healing touch non-crit ? Can anyone confirm if mastery is affecting it or not? in general 7 casts of healing touch and 290k seems way too low.. based that healing touch is doing much more even non crit. (isnt 3 treants x 7 casts x healing touch ??)
Lets see what new patch bring us!
