Yeah, they advertised the game pretty heavily with the co-op angle, which actually got me to purchase it, as I've loved "co-opping" every Halo game with a friend... but to have basically 2 armor sets available from the vanguard vendor in PvE and 2 armor sets from crucible vendor, 2 armor sets from all 3 factions and 2 from iron banner is making me feel very left out unless I force myself into PvP, which I a) am not that good at b) often have bad experiences with.. It's just becoming quite frustrating, to say the least.
