IMO switching to a different set of armor isn't cheating, but its giving you a pretty unfair advantage to hit 10hp/s regen and hiding around a pillar to heal quickly. I'm guessing your armor set was custom battle and some form of one of the new guns (epic shotgun, epic revolver), because my hp regen is 10/s when I use that xP

Using this strategy will definitely give you the upper hand instead of a fair fight. Use at your own peril of the other team crying and team rushing xD I know that if I fought someone who did this I'd call the fight off to save my terrible kdr further humiliation
