Ok and hi.
I tested your map a bit (only runned around there didn't have other players) I have some own intrests at reverse flag maps and I like to develop them so I shall poit thinks that I think should be difrent.
I do not know how much you have thinked abouth your desing before but one think I know for sure is that reverse flag maps are super hard to make.
Since think it a bit. You actually need to have the flag at opponent base while your own flag is returned. So the capping needs 2 thinks. Returned flag and flag carrier at opponent base. It is pretty hard to cap at map like hormone (it is lot of played and tested so I know that it is hard) Even when the map is REALY small and REALY simple.
So first think to do. make the capping easy as possible. otherwise it is just pure luck if there ever happens caps.
In your map there is allready 2 main routes. So it means team need split. It is likely flagger + some other guy to one route. And the last guy for one route. I woud use tactic where flagger goues to up with some other guy and 1 guy to low (since it is easier to attack from up it is better to have 2 guys there) so the down guy would "defend" and kill the guys that retriet from strike from upside.
In my poit of view that "flag trow" option only helps defender. when the situation looks hopeless (and it looks hopeless only if both ways fail) they can allways toss the flag from the bridge to buy more time. So in the result there won't be likely caps.

Same time move spawns! My paint picture might not be too beatifull but I think you got the idea. and take the bridges away from the base. full it with land or let it be. (I am not sure whitch one would be more benefitting abouth making easy caps) in other hand it gives more change to run away. And in other hands it gives changes to attack from there too. But simply is usually effective so I think it should deleted. (But I am having fear that this will be too hard to cap still) But the flag trow option there would make possible the capping if just one guy survives to the flag area (when the flag is there) so someone would just toss the flag to him and vola! cap!.Hhmm Maybe you should make some kind of bunker to the old spawn area that solo survivor could live longer for possible cap.
There aint too many working reverse flag maps out there so it is nice to see that soemone else tryes too (well hormone works and bunch of copies from it but copies are just like the hormone so basicly there is only 1 working reverse flag map) Good luck with your future developping I am trying to think something too... This is just so hard.
