Recently i've switched from healing to shadow dps. I pull alright damage but i recently changed my UI and some reforging and i noticed a dps decrease last week. What i did was i went from roughly 2.6k haste down to 2.1k and put the rest into mastery. I did this and noticed a decrease in my dps. my armory is here http://us.battle.net/wow/en/characte...thric/advanced and here is my guilds logs http://www.worldoflogs.com/reports/rt-7umjm7ir4rh2gt8g/. If you need to know anything else i will reply. Sorry for the bad English it is not my first language
*Note i do not have a 4 set or a staff but i had DI!!!!
