I can't believe they gave corner/wall hugging as something to use. Obviously other ranged classes can also do that, BUT they also have even more tools to deal with melee, defensive cooldowns, and/or good mobility. Couple changes I would do:
- Barrage procs allow that Unload to be castable while moving. This gives us a snare on the move (FINALLY) and some damage mobility.
- Lower Thermal Sensor and Power Surge CD's to 1 min. Or Allow them to have stacks to give the next 3 or so abilities to get the effect.
- Move the PowerShield talent in Bodyguard tree to switch with Superchaged Gas.
These changes wouldn't be very difficult IMO, but would really improve gameplay of the class.
