Ya if you want the extra damage you almost have to use feint glyph for 7 seconds. Either way Sub fun but adding another thing you have to/ should keep up makes it tedious and clunky to me. I mean ya you don't have to have SnD up or feint but your just hurting yourself if you don't. They should bake this stuff into others. I think Sub rogue is the only class that has more than 3 buttons now.
feint glyph does nothing for the 4pc
its always 5 sec versatilitybuff
