There's no good reason for it. I just quit games that start on these maps.
Help me understand the logic in 20x20 4v4 maps in 1v1 map pool
The logic is quite simple.
Larger maps > increased probability of longer games > increased probability of the games scope being realised (i.e. nukes/experimental/technology three units and strategies of eliminating the enemy armoured command unit) > which for many players ultimately translates to more fun.
In smaller maps, especially 5x5 maps, you are lucky if you get to use 25-30% +/- of what the game has to offer in terms of its units and the strategies available to kill an opponent.
Granted this may be daunting in a 1v1 game and can be drawn out and even "boring" for some players. But there are players that enjoy this, even in the context of 1v1.
They enjoy long games consisting of big battles, not short games consisting of short battles
@funkoff there's 2 in every pool if youre over 1200... compared to like 8 smaller maps AND frequent mapgen. You cant please everyone
@funkoff if this is what you bring to ladder than please just stick to custom games where you can host your own map the way you like. Quitting on people after they have waited in que is selfish and toxic.
