Great. Now imagine if you were using one of the top tier dps classes? you'd be doing about twice as much dps if not more AND also providing utility to your team.
Im repeating myself. Again, I have a sentinel in aug'ed warhero, and I'm at least in the top 10% of sentinels on my server. I do well, but no better than my commando.
Oh, and I have no problems with gunslingers at all in a 1v1 fight. They really are turrets, and as an assault commando I'm not. Sticky, assault, light on fire, HIB. If I see those targets start to close in on me, I duck LOS.... Maybe even self-heal and then re-engage. On most maps my commando can beat a gunslinger 1v1 9 times out of 10.
