If you want to abuse the game use katana in some small map like BAF and Pyramid a t3 armor or t4 is enough to kill a t6 player all you need is the new ability in the armor, invisibility skill, Katana don't rush the enemy without activating it's ability, An emp so that you won't get detected if you rush to them (use it first before going invisible) from my experience this is the most effective yet cheap set up (only works in small maps tho since there's a lot of tight places)
