Man great map!
I love the HUD it's awesome and works perfect! The spy being able to hold the flag while disguised is classic...dk how many stabs I got on the enemy b/c of that
The lack of signs really isn't too bad...there are arrows and although some places are confusing, after about 10min on the map I had it pretty well down.
The only thing I would suggest is that you make it so that the flags can not be taken into respawn. We were talking and pretty much if on a 5v+ you could take 3 players and have them sit in spawn and then take on flag to cp4 and just have 2 guys easily defend it. Might not happen often, but it's definitely a possibility. If you put up a trigger at each resup entrance that checks for flag and forces player to drop items then I think it would be perfect.
