So far it seems that pretty much everyone really like the big GSL maps - Tal´Darim Altar, Crevasse and Terminus Re.
As a result these maps have now been included in a lot of tournaments. However I believe we should have legitimate concerns about this trend to use those big maps in a map pool.
The main concern is that really big maps rule out a lot of builds and units that are viable on smaller maps (but in no way small) like Typhoon and Shakuras. This may not be evident just yet cause the maps are still new.
As a terran, going pure mech can much easier be exploited by his opponent as there is much more space to move around.
A huge protoss ball can also be dodged more easy.
Personally I am a zerg player and I am afraid that the only viable build vs any opponent will be ling/bling/muta. As I see it mutas are an absolute MUST HAVE on these big maps. No infestor play. No roach/hydra combo as they move too slow and need to be clumped up.
My question is: Do we really need these big maps to get good games and a balanced gameplay?
I dont think we do. In fact I think, that because the build options are more limited, we will get less entertaining games than we currently have on maps like XNC, Shakuras and Meta. I would like to add Backwater Gulch, Typhoon Peaks and Shattered Temple but I just havnt seen any pro games on them, which is a shame as I think they are great maps.
TL;DR - The big GSL maps restrict the gameplay and force the players to chose from just a few viable builds.
