adding a pernament freeze time at start

[Dr.McNinja]

Um, im under the pretense it would be something like dota, where you can move around and buy or whatever you want to do but troops wont spawn. In bt, you would need to stop people from attacking enemy towers too. Disabling cp-tp for this duration would be sufficient, since walking out would take as long as the 'freeze time' anyway.

And to buy weapons before moving would mean having the weapon shops in range of tank starting locations.

So no creep spawns, cant cp-tp for 15 seconds would easily work as a 'freeze time'. Theres a lot of names for it.
