Hey, Venguard. We've been playing your Deadend payload map on our Payload Extreme server at No-Heroes.com. We love new maps (currently running 24 maps on that server) so it's been getting some play time.
I think the one complaint is how difficult it is to cap the second point. Just a couple of engies can hold it w/o too much trouble. As a suggestion, moving the Red spawn back to the final spawn point after Blu caps the first point might help alleviate the bottleneck. As it is now, Red practically spawns over the action.
Feel free to pop by the no-heroes.com forums if you want to say hi or get any feedback.
Thanks for the map, btw.
