This makes sense on surface but I think this game/map "design" could potentially change the game "balance". For example, Zerg usually expands because they want the gas and if there is only one gas in every expo, that could potentially hurt them more. Keep it in mind that this is just ONE example.
Don't get me wrong, I think less workers would make the game more exciting. 6 workers in each base for gas is a lot. Especially, in the late game when you have 4 bases or more- that's at least 24 workers just mining gas.
What do you guys think about this? Here are some suggestions.
1. Blizzard can change the gas mining rate twice as fast so that every base will only have one gas but you would get the same gas as you were mining from 2 gases in current state of the game.
2. Just one gas for every base and the gas mining rate will stay the same: ex) tech switch won't be as easy since they require heavy gas. But the game will feel like less "money map-ish" like brood war.
Feel free to tell us your thoughts.
