This is the talents i went on mine for a bit but the only problem that i found with it was losing lots of mana from wasted dots considering the burst damage you can do (2 instant sb immolate conflag shadowburn) but on this build you need lots of shadow damage + spell crit its not really worth it if you only have a 15% chance to crit and fighting someone with 400 resil decreases your chance to score a crit by over 10% and reduces the crit damage by over 20% but in the long run you will be out dpsed in bgs by straight afflict locks
