I have played about 2100 games, only won about 1050 of them. Race wise in solo I haven't done well this season.
I have only played 11 games of solo and 12 games of FFA (FFA was the pits). The only acceptable one is vs NE at 50%. I am at 33% at the rest. I have only soloed with Orc.
I don't got problems with NE, since I liek to use pults and smash thier unarmored minions to splattered guts. Also, I am ready to change my strategy in both 2on2 (which is now the only form of RT I now play, which is good because it has its solo players and its a challenge) and Solos.
Same with human, since I like to carry sws along, and I dispel when too many of my units are slowed or morphed. Then I use my blademaster to attack the casters while my other guys takes on thier heroes and units.
The only real trouble I have is Orc Mirror, since Tauren can be a pain in the ass without magic damage.
However, once my record is closer to 49.5 or something, I will go back to solo.
