The changes to mid are pretty awesome. The healths are ok, someone said something about them not being in the right place, but i had no quarrels. Deffinately don't move the small in the intel room. My only gripe is that grabing the intel as a team, leaves the scout running off to cap, and 2 or 3 people right outside the enemy spawn, on the high ground.
The reset is a little annoying, but it also means you have to protect the flag carrier all the way to your own base. I would say leave it, so a team didn't stick around to spawn camp, but it's annoying when a scout runs between 2 protectors and the flag carrier for a sneak return. This would probably work better in pub play, and i don't play comp so i can't really say whether they prefer this mechanic or not. But it seemed that in general you should remove it.
