Try to team up with your friends and do the Raid. You eventually will get exotic drops, or you can do the weekly strikes which you will get strange coins from that can be used to buy exotic armor/weapons.
g19 is a hardcore Destiny player. I think RJTB is right, you need to do raids (Crota's end hard mode) and get some exotic drops. Maybe, just maybe, you can hit 32.
I think I need a new helmet. http://www.mediafire.com/view/uzepccp4po2i4co/Untitled.png Here is a link to my player so what you think.
A raid should do the trick try doing some raids and eventually you will get some engrams and you can unlock a nice helm.
You need atleast 3 raid gear and 1 exotic, or 4 raid gear to hit 32. If your online on the next raid i will hit you up again. We can cheese pretty much the whole raid now. but you have the gear just need to upgrade them. Best way to upgrade/level them fast is to do bounties,strikes, and raids. if you are up late you can do the double bounties trick to level them up fast. but you stil need to do raids to get radiant shards to upgrade the armor peices. Do you only have 1 character???
