Anyway, I think the aproppiate rules are:

1v1:

Max 4 HA.
Max 6 missile (Footmen).
Max 8 cav (Melee).
Max 6.
Max 2 chariots/1 ele.
Art allowed.

2 v 2:

Max 6 HA/team.
Max 6 missile (Footmen).
Max 8 cav (Melee).
Max 6.
Max 2 chariots/1 ele/team.
Art allowed.

3 v 3:

Max 8 HA/team.
Max 6 missile (Footmen).
Max 8 cav (Melee).
Max 6.
Max 3 chariots/2 ele/team.
Art allowed.

4 v 4:

Max 10 HA/team.
Max 6 missile (Footmen).
Max 8 cav (Melee).
Max 6.
Max 3 chariots/2 ele/team.
Art allowed.

Zerkers max is the same as HA's.
