Could you link your armory?
But I'd say , go for 15% hit .
Then gem 320 mastery in yellow sockets.
80 int + 160 mastery in red sockets.
160 hit + mastery / haste in blue .
15 % hit and for now try to get to 4717 haste rating. Keep mastery at equal level or a little bit higher.
At least that's what I've gathered from all the shitton of information written in these threads.
No need to refresh dots like crazy, that's a dpsloss.
Only refresh when it's under 50% duration left (or if you get proccs and such.. like bloodlust/trink proccs) .. Get the "Affdots" addon, it'll help.
Keep dots up, use malefic grasp , refresh dots when needed, use haunt when you feel you have shards for it.
For just elegon .. Keep dots on elegon, dot the big add, during the small adds i personally use fel flame since they tend do go down faster.
Anyone that knows better, feel free to correct me.
