Once I get my 4pc T10, I've heard that it's worth it to switch from str/crit to str/haste gems in yellow slots(if the socket bonus is good enough, of course). Now, I know I"m not there yet, but I was wondering if I should start saving up my JC tokens from dailies in order to buy the str/haste pattern so I can cut it myself, or if I shouldn't bother because straight str (or keeping str/crit) gems would be better, even with the increased value of haste due to the T10 set bonuses.
Feel free to eviscerate my ignorance right after you answer my question.
I have several other characters that I regularly work on, so I don't do my dailies every day. Also, most JC tokens that I get I use to buy dragonseyes to sell them (buying all the saronite for my SE has drained my personal coffers).
