The current system is not good for Duel. Too many standard servers are empty. We are not asking to have ZTN or HUB every month. We are just asking for playable/decent duel maps ONLY in duel. 

The current rotation has space camp, devilish, terminatria, cure, and toxicity. Devilish and Terminatria are too large for Duel and space camp is a joke map. Ok, Cure and toxicity are playable they are good! BUT that means a server that is stuck on a very unpopular choice (Devilish Term Space Camp) will most likely be empty.  

Looking at the North American Duel Servers Right NOW on Saturday 3:13pm EDT, every standard server is empty. All these standard servers also do not have cure or toxicity chosen.
