Hopefully you don't mean the building section of the cave flank, which is supposed to have a roof - otherwise, yes "cave" has been roofless for a number of versions.
Choke has been that way for a looooong time, haha. I do need to properly clip it (the middle chunk of it is a "true ramp" that you can slide off of, etc. but it's not quite big enough, makes jumps seem inconsistent here and there) but otherwise it's been OK.
The dropdown needs tweaks as is, but was definitely designed to be a very easily spammable and visible location. If you're going to be there, if they don't pay attention, you can win; but if they are paying attention, you eat spam.
I am bummed that ETF2L and ESEA both haven't given it a shot - but stoked to see what Ozfortress brings.
