I increased all spawntimes, that is what caused it to become more stalematey, and I think it's a step in the right direction. I think I can achieve balance if I reduce them just a bit in the next version. That should get rid of the problem of cp2 being too easy to defend too, as in the last version it seemed too difficult to defend.
Also, it's good that you pointed out the grate thing, I hadn't noticed that myself. I'll remove it's collisions or something to make it impossible to climb. I'm also working on the optimization.
