Don't look too much at QM rating. It's a lot of an activity score more then a raw competitive rank. Most of the competitive warzone is played elsewhere.
I specialize in Small Earth 1v1 Auto Dist
Don't try to get good at small earth. It's terrible for learning deeper strategy. To get good at the ladder, play the ladder games ;)
That being said, it sounds like you are looking for a clan? Plenty good clans here. Also as a starting point, make sure you know all the stuff in the MH guide for 1v1 ladder play http://tinyurl.com/MH-strategy-guide
