I <3 taking down the Armoury during SD (on servers where it can't be rebuilt)
what happened Humans?
little pink Alien eat ur gunstore?
waaaaah....
it iz 2 lol
It might be fun but is it fair? Do the aliens have an equivalent structure which is so easily taken down and causes so much loss for the team? I'd say that, at later stages of the game, the major purpose of the reactor is to power the armoury (..and to a lesser extent- the medi). The aliens on the other hand have armouries+medis inside themselves, of which the medi (heal) doesn't, currently, need the overmind to function. Their major structure (which powers their in-built armouries) is alot stronger than the human armoury and heals itself. When the humans haven't spawned as builder whhile the armoury is down in SD, they can't heal the reactor which is only there to power their medi, defences and nodes. This is usually where those silly human camp instead of leaving the base to get destroyed.
If you want to balance SD, the humans should be able to shoot and destroy a little green dot on the aliens back which renders it unable to evolve even after respawning.
If you want a better solution, don't use SD.
