I personally love Albatross and have great memories of playing it back on SGM. But I think it might best be reserved for high pop because of its size. That and what you said, the door blocking can be funny but god damn is it a bitch lol.
I like the extra prep time at the start of the map, but I don't know if we need a WHOLE LOT of extra time. I do find myself scrambling to buy t or change my load out in between rounds 2-6 sometimes tho lol.
