2TMNT: The phrase about XL in a month was hilarious. Of course, if you create a map like many found online, with just 4 trees and two rocks on 144 cells, then yes, it's possible to do it in a month. Otherwise, you simply won't have time to reach the enemy if they are far enough away from you.
By the way, a question for those in the know: is there a resource that provides information about world championships in Heroes? If so, please provide a link (I'm not participating :)).
Regarding the topic: An experienced player doesn't care which faction to play, because they are experienced enough to see the advantages where others see the disadvantages.
