Before you all start trying to gank me for saying the HLS is actually useful, try using it in Oddball.

This is actually a really good load out. Keep in mind this is an objective game type, not slayer. The goal isn't to get as many kills as possible, the goal is to win. The AR will do a lot of damage even if you die, your teammate will finish the player off. I go 15 kills per game mostly, with about 15 assists too haha.
I tend to take a few bullets, throw up the shield while waiting for them to take the opportunity to either reload, or run their clip out, and finish them off. I will also try to melee after they throw a melee onto my shield.
It's not a perfect strat, but it works wonders. Try it out.
