IMHO players should perfect tma in sp then join us veterans in mp.
Thats how i did it (In SC) perfected it there then when dw came out moved to MP. Otto can go back to basic remove it from game i say. Untill then make sure that theres a nice honest host who keeps Otto turned off and have real fun trying to find your opponent before wasting missiles and the like on them.
Go Molon tell em all. Keep Auto Off.
