What wep ability or cast ability should I be uping on my rogue? also how much % should they be at?
Since you are going Melee, I suggest using the Rogue's ability Backstab, it hits the back column, and also pickup another one, maybe Knockdown or Powerstrike, those are both good ones to get even though they are not the Rogue's specialty, they work very well with any melee type build.
If you get Powerstrike, it can be fairly effective with only a few points invested.
Backastab and Knockdown both would want more invested because you will use them a lot more often.
When you charge them up, try charging them to ~100% and then use them, because if you charge them to 200% it is a bit of a waste.
