So my guild has everything but Illidan on farm (who will be dying next week). Assuming I'll get all my gear, and that I'll have all the sunwell items that I want, I should have a 2.24 cast on my shadowbolt. What I'm wondering is whether I should gem for crit or for haste. Two of my sockets are reserved for 4 haste and 6 stam for my meta (this is included with the previous mentioned cast). This leaves me with 6 sockets left (I'm not getting the t6 chest). Now, the question is whether I should get crit or haste in that. 48 haste vs. 60 spell crit, or bringing my shadowbolt down to a 2.18 second cast or gaining 2.5% crit plus 5 spell crit rating, I don't know the conversion of one spell crit.
To get the main point of the thread out of that paragraph, which is better: minus 0.06 seconds on my shadowbolt cast, or getting 2.5% crit and 5 spell crit rating.
