you appear to be simmed, gems and reforging look good if you are. No complaints on spec, assuming u change a talent or 2 for certain fights (mainly thinking incanter's instead of rune). Try minor glyph of teleport, nice 1 minute speed boost racing to the bank/auction house. Try cone of cold instead of combustion. Its all situational tho...look good but minor tweaks based on fight. Drop the stopwatch if u can get the other heroic 463 trinket. Keep an eye out for Serpents cards. In a single week ive seen individual cards (for example the Ace) drop dramatically. Today Ace of Serpents in 10,000 gold....in a couple days there might be 15 aces up in the auction house as cheap as 1500g. You could assemble a deck for prolly 10-12k gold total with alot of patience and auction house checking.
Your good tho.
