There are a handful of maps that are widely regarded as tournament material. They are carefully analyzed and played often to ensure balance. I totally understand that, but what I would like to see is maps being used that pro players have never seen before. Here's how it may work:
Before a tournament, new maps would be made. Care would be given to make sure the maps are as unique as possible as well as fair as possible, given a short amount of time to make them. (The idea isn't to make them perfect, more on that later.) Upon tournament day the maps are revealed to the players. Perhaps they aren't shown until the loading screen.
The point of this exercise is to test the adaptability of the players. It's one thing to memorize engagements and be skilled at a certain map. It's an entire different thing to quickly assess a new battlefield you have never seen before and make decisions quickly about your strategy and such. To me, someone who can think on the fly successfully like this is typically a better player than someone who is mechanically adept because he's played the same map 1,000 times. At the end of the tournament the maps are discarded and not used again.
Now, you may be thinking to yourself that it wouldn't be fair or the map may be unbalanced in some way. The point of not revealing the map until play time is that there is no time to abuse any tactics that may be present. Furthermore, the maps are generally discarded so the next time one of these tournaments happens all the maps may be fresh again. This could be a lot of fun for the audience as well as the map reveal would be surprising to them as well.
These kinds of rounds could be bonus rounds or specially made events for these special tournaments. Just for fun or whatever, until the bugs get worked out. Anyway, I think the point is clear. I really think this would be fun to watch. What does the community think?
