"ultimately what matters is how the games on it play out and if they're balanced enough for competition and ladder."
100% for me. Newer/different maps are much more likely to produce wonky/short/weird games Don't get me wrong I love them too, especially seeing a desert or ice or ash tileset map which are pretty rare now days.
At least we got the New Worlds Map Contest though.Anyone's welcome to create and submit maps, collaborate and all the decision making is public/democratic, with a chance to get the maps into leagues (Including ASL and ladder). If there's a time to be map making, it's now. Can't ask for more than that.
