Deception at the moment isnt viable. DPS wise the Deception is so far behind from other classes, tactical Items arent rly great, you could also delete them from the game, had to use Luck always changes to achieve some higher Crit numbers. Had to play with high alacrity and low crit to achieve higher dps(on a heavy crit based Class btw) tested it for some Hours, also tested it with a High Crit and low alacrity build with bad results, maybe you should think about bringing it back to Patch 5.5 levels, so the Deception can compete better with other Melee specs.
