Bandit's guile makes it downright impractical to play combat on most boss fights, which usually involve adds/ multiple boss targets with lots of switching and whatnot.
The restless blades change is a godsend and I think it will be a HUGE step toward putting us back up with assassination in terms of maneuverability.
I am very happy with the new change to MG, and I'm sure that'll be a big help towards making mastery less useless to us. However, that brings up the issue of what it's worth versus our previous best substat (after hit and exp caps ofc), haste.
