tried that but units moved way too slow in the water, it would take forever to get somewhere. noone used it.
Imo better to have it as an OPTION , than to not having it crossable at all. If people don't want to cross it , they don't have to go there, but some might use it for ambush with cloaked units etc.
so i tried to make land passages in the middle but tbh, it looks like shit.
Maybe some mini islands and between them water that takes like 0.5 sec to cross.
