As much as I would overall, prefer to see multi-environment servers in TM2, I'm not too worried about it right now. For example, the MX Knockout's could benefit from rotating the single environments, as each week becomes different from the previous and this pro-longs the life of each map pool.
Infact, seeing as we usually do 2 KO's per weekend, we could have an alternating schedule as follows...
Stadium / Canyon
Valley / Stadium
Canyon / Valley
It looks more interesting than
All / All
All / All
All / All
