Get your alacrity to around 8% percent and you will be fine. The tooltip will show a difference in vast times between 8% And 10% however the cast time will still take the same amount of time. For example, when my sorcerer is a Lightning DPS, force lightning takes 2.7 seconds (without polarity shift, lightning barrage and the 4 item set bonus) to cast at 10%. Wheny alacrity is at 8% it still takes 2.7 seconds to cast even though there is a difference on te tool tip. When my sorcerer is healing, the alacrity stays the same but I lose those nifty procs.
Oh top job btw, too busy arguing with losing Jedi's
8% is a good max, 32% crit unbuffed and just over 300 surge after these numbers you just aren't going up as much as you'd like. Don't rush to the 8% alacrity though, you'll pick some up along the way, just look after the other numbers first......plus......get Willpower, ie main stat, on all augments is allways money well spent and time too.
