Oh well, back to the original point for me I guess :
Shuting down turrets sure helps the SD end faster but I don't see any argument why it would make SD more balanced. Once again, the point here is to make SD balanced, not to make is shorter.
On the contrary, if the turrets shutdown at SD I'm sure a single alien marauder without any buildings left could take down the human base ( armory first, reactor second ) and kill the defenseless humans one after the other once they run out of ammo. This in my opinion would be a major imbalance in favor of aliens in SD which is exactly the oposite of what we are trying to do here.
So, before we go on a version with ( once again, IMHO ) such a broken feature, maybe you could give some arguments as to why it will "fix SD" before.
On a side note, I'm sure it'll be dead easy to implement though. Since the game already supports shuting down turrets with the reactor/overmind is down, it's probably easy to add a small condition testing also if we are in SD.
Also, I didn't talk about the limited respanw because I didn't have much opinion on such feature. Very hard to make a guess as to what will be the effects in the game. Still, I think it favors aliens : good Tyrant players do not die often and a human player without armory needs to die to get ammo and fight, aliens ( dretches ) do not. And last, I think it'll cause even more camping during the SD since dieing means losing the game.
PS : don't you feel like an Alien player that likes it's SD advantage pitched against an Human player that fights to get more balance out of that part of the game? I sure do in the end

Your post opening starts with
[qoute]Allowing armouries to be rebuilt would make the human SD more even to alien SD, but I think it takes away any likelihood of a lucky alien win.[/quote]
It spells rather clearly that you do not want to balance that part of the game

Probably what have sent me of with the agresive reply.
