Here's a list with all the boost exploits I found, I think most of them weren't intentional:

Also, about the pillars on tunnel (mid side), the way you put them, puts the CTs into a disadvantage. It's already hard enough to win a round as a CT, don't make their lives even more difficult.

Also I like that you increased the visibility in most areas.

All and all, good job and keep it up.
