So basically what your saying tanks that are wearing dps gear is an exploit design flaw from bioware? interesting
In the case of Shadows and Assassins, he's partially right that there's a flaw. A Tank wearing DPS gear can work, but shouldn't work so well that it's said to be better than full-Tank. In this case, a part of the problem lies in the lack of effectiveness of Tank's stats, and the other part comes from the fact that the spec offers a pretty good synergy with DPS gear.
