Hi. I've played mage since WotLK. Played through LK and Cataclysm completely. I stopped playing after reaching level 90 in pandaria because I had a rough shift and lots of other stuff. I've seen how things have changed. I know I still don't have the metagem but sometimes my DPS is garbage. My ilvl is 537, I believe. I came across the term snapshotting. I thought mages dots look at SP constantly before ticking but I believe that is not the case. My question is, how vital is snapshotting for a mages DPS? How much increase in DPS can I expect? Tools that help facilitate track those moments to snapshot a DOT.
