why you do this
The island one is spammy and on a rather low quality map. Use one of the default ones, and if you still can't, use plate 3. Don't use the map as your own build.
The city one looks dull with giant cubes as skyscrapers, no points of interest and simple roads. Not to mention, when I played it, all the gunship copters ruled everything. And half of the battle went on, underwater.
For your canyon TDM, you're looking good, but you most definitely should cease that Rykuta junk weapon package.
Edit: Oh, the video moved on. I should also mention that you shouldn't mix lots of weapon packages at once. And the build DOESN'T look good from your F8 view.
