My issue with big maps are the following:
Bases mean very little. With so much territory, there is very little incentive to defend against a large group attacking. Those who might up to make a fight out of it, may instead look to an area which at the moment has more action. However, once an upper hand is reached, the other team seems to disappear, and move to attack a base which has little opposition. This cycle in itself is not bad, if, and a big if, they didn't overlap so much. Basically, If you are losing one base, who cares, just up someplace else and take an undefended base. You end up with fleeting resistance, with the enemy chosing to move away from one battle, and attack undefended territory, while the other team continues to attack a base, that was once populated.
I understand the strat of all this, but imho, it leads to some stale fights, with one team with a large upper hand at one base, the other with an upper hand at the other. It becomes difficult to defend a large area, because of the overlapping time it takes for one group to drop everything it's doing, and move to where the threat has moved. Leading to the notion that there is more milkrunning. I understand the idea to up and defend a base, but the overlapping time is a limiting factor.
Large maps offer lots of different type of play. You will get some smaller fights, you will get some large fights. But it seems, to me anyway, the norm is a larger groups attacking areas against very small groups. Where on smaller maps, the battles tend to larger, more constant, and sustained. However, this is at the price of less small fights and less options. On the other hand, large maps don't seem to be reset very often at all, so victories are far less common, having a muting effect on win the war.
My conclusion would be there is somewhat of a paradoxical effect, In the some strat guys might like larger maps due to the availability of fields to attack, but at cost of not being able to win the war. Large maps can have large battles, but often the end quickly, as people look for many opportunities at another field, in which they will have advantage. Smaller maps tend to force more action in certain area's. Just my thoughts.
