To be honest your best bet to hit 32 sooner rather than later would be to use an exotic helmet, combined with raid chest, boots and gauntlets. It might not be your ideal setup. But for now at least it will get the level people are asking for in order to join there FireTeam. I prefer my team mates to be 32. Although if a 31 can pull his/her weight and without dying. I don't mind long as the vast majority are 32.
