I mostly build around gun damage, Kinetic Carbine and high movement. I try to be aggressive in lane, then roam the map looking for ganks and split-pushing opportunities before carrying in the team fights. The Pulse Grenade is only really important for area denial in laning; later in the game it just gets relegated to clearing waves and jungle camps. I used to build more into cooldowns for the classic Paradox combo but at my level getting picks in a team fight matters a lot less than just being able to hard carry through raw damage output (because players are unorganised and generally pretty bad) and I am winning a lot more since switching to a DPS carry kind of role.
