As promised here's a quick look at the rough idea for choke in RC2:

I wanted to get rid of the natural rock cover to make a distinction between choke and cave, thus the little bridge to prevent bombing from a million miles above.
I have removed the little connector between cave and choke- it seemed that there was no nice way to have it set up with sightlines being right to have it there anymore. Plus, with how I moved cave's entrance on 2nd much closer I don't think it was as necessary- cave used to be a huge long connector and that cut it in half- now that it's lost most of it's length I think cave should be fine without the door to choke.
I also made the middle of choke the high ground- after doing lots of analyzing and looking around it's pretty clear why this is really the best option- limiting sight, keeping the lines of the map fluid, without giving either team a distinct advantage. There's a few sniper sightlines that have creeped up with the rising of the ground- but like I said this is rough and I'll work on tweaking before I release.
Merry Christmas all.

(Edit: Sorry for the viewmodels and hud in the screenshots I've got something up with my cfg that's not letting me change anything in console... I'll figure it out.)
