I don't have this and I have 49 total exp... any reason or do I need to get all the experience while playing one time??

'cause it counts from one playlist(any list) and only one. When you'll get 20exp on any playlist it will pop

I got this achievement today when I reached 12 EXP. I only played Lone Wolves for all 12 EXP. So the description for this one isn't quite accurate, perhaps it also depends on skill because I think I reached 10 skill at the same time?

You have to have 20 EXP and 12 PXP overall. EXP is simply experiance overall, Gathered from any of the playlists. PXP is playlist specific, Such as playing lone wolf so much that you get 12 experiance from that alone. So play until you get that total EXP and PXP (in a set playlist) and there you go.

I got this when i gained 10 overall experience, all of which was for one game type, so 10 EXP and 10 PXP.

I got this @ 9 PXP and 20+ EXP. I think that 12 PXP is an average figure for the achievement to unlock and not a definitive one. It seems the better you do in your games (i.e. placing in the top 3 in lone wolves for instance), the quicker you progress through the ranks. I've seen people with 7 EXP and have the sergeant rank. I don't know, this Playlist XP is weird, its almost as if Bungie is punishing less skilled players for playing their game.
