I agree with some screenshots from jao.
I agree with: 1, 2, 5, 6, 7
Abobut 3: I agree about the start, add stoppers -> fixed. The time reset is maybe not even a big thing, since you can play in groups and wait before spawn. But i prefer stoppers (still rather mappers choice)
You only need to do the hammerthrow to the right. If there are other tees, the whole group can go up with the other tees. There is not really much blocking unless they are retards. But they will realise that blocking is dumb there (we also have kickvotes).
4: how to die there? you can hook him if he is at the bottom of that drag part (i tested it).
5: maybe 2 tubes are enough (i don't think they will sit there for years), more space would be nice and usefull.
6: why is there even freeze at the ceiling? not even the easiest hammerhit. if you want to teach hf make an easier part with teleport and more space (so groups less likely block themselves). this seems to be too much compared to the other parts.
7: add a platform to take dj easier, then there is a way for noobs to help (hooking + doublejump -> getting dj; repeat). i am not sure about the warn sign, rather mappers choice.
After some rebalances this map seems playable for me, so there should be no reason to not release it.
edit:
i don't like freeze here, it is not really marked (well it is hard to marke freeze and undeep). i don't see a reason to put freeze here
