I spend about 4-5 hours everyday just clicking refresh on custom games and joining and helping with almost any maps. I also give out random trans and myth sets to help people break into NM (I've been there, it sucks breaking into NM. First wave of Endless Spires, anyone?) And whenever I do lab runs for myself, I always leave 2 open spots for random people. Granted all of what I do is just to help people stay in the game because no one likes getting stuck and not being able to break into harder parts of the game. I also used to do a request lobby, but I got annoyed by constant requests for WW, Silent Night, and free high end gear. I don't mind progressing players, but at that point, it's not helping the players, it's just doing the game for them.
P.S. Add me, I'd like to donate a few cubes to the raffle as well. And if I win, I'll drop the cubes off in random taverns to help newer people out.
