Man Slut, everytime we AT (Me you Ted and tweak, ocassionally Treefrog), we get owned cuz they go mass ghouls/footies/arches + hunts/Grunts and then all 4 attack one base we dead.
I prefer solo because you can actually sdtand a chance with a big army. In AT even if you have a fully upped good army of...let's say as Human, about 6 Gryphs, some rifles, 2 lvl 6 heroes, and some casters (Spell breakers as well depending on the race, especially good for Orc to jack their Bloodlust), yu could get owned because you'd have 4 full armies on your base.
I'll AT with you on 2v2, because I can deal with 2v2 ATs, but anything higher and it's no fun.
