It seems to me that this isn't a crucial issue... As long as the opponents are on equal footing, and it's completely unknown which faction each player will choose at the beginning:).
New here? I'm Roha — want a quick tour?
I checked, in h3dm1 it was a bug in the template. I assigned teleport types randomly, forgetting that they come in different sizes. I'll fix it.
Was this fixed? I downloaded the template from the link in the first post, but the various teleports didn't disappear, which was quite unpleasant in yesterday's tournament match (although not critical).

The map size is probably not correct. Try using a Dungeon map – M+U or L+U.
