The middle point should be moved from Windmill to Market
This would concentrate the action mostly to the lower half of the Crystal Scar, making the bottom lane less of an island. As an added bonus, this would also make it abundantly clear that Jungle Control is the single most important aspect of the map rather than pulling players into trap options like pushing toward Windmill.
This would also leave Windmill open to more interesting uses. A big powerful neutral monster of some kind spawning up there would put enough distance between the objective and the rest of the capture points to prevent a won objective from instantly snowballing into a 5-Cap.
We could call the monster Tamat the Destroyer. His main sources of damage could be moving Dominion topics from GD to the Dominion boards, and then erasing the Dominion boards.
