[bug] arenas 9721

[The_Game_Master]

Rev: 9721

After revision 9721, you can no longer join 2v2 / 3v3 / 5v5 skirmish or rated battles.

[Voldemmort]

It has something to do with the battleground_template for the arenas that has min max team players of 0/2, just change the 0 with a 1 and they will work like before (I'm not sure of the 5v5 but the 2v2 and 3v3 will work)
