So, as I do, I went testing Water Hazard.
After a few games on it, I can say two things.
First, things load slower on Water Hazard than other maps. It takes about a full second longer (on my PC) to render things in Water Hazard compare to other maps.
Second, the bridge is a little glitchy. Sometimes, the textures missing. Sometimes, they look like rainbows. Sometimes, they are jagged triangles.
But my conclusion is that none of these are game breaking. First few seconds, and sometimes few minutes, in GOIO is introductions and strategies; longer load time isn't a significant deal. Bridges are glitchy, but that makes it something to be fixed, not removed.
I for one find the bridges and structures in Water Hazard aesthetically pleasing. Others seem to find tactical use in them. Bridges should not be removed in Water Hazard.
