There should be some kind of building allowing you to build forward bases without the other team destroying it within a few seconds (sometimes).
To change that idea, decon buffer.
1st structure deconned will be the one which you will build at the forward location.
All other structures deconned will have their position relative to the first one saved in the buffer.
Build the first one where you want it, the rest will pop into existence building at the same time as they were relative to the old location. Give it a 0,7 reac buildtime.
This way you'll have to build that base in advance, take it down, move and build all structures at the same time.
Prerequisite. You need to build the base first anyway and in no way does it really protect the forward base from the start of building.
It simply means that you don't need to build a repeater, wait, turret, wait, get killed, wanted to build medpad, etc. And aliens still get a chance to kill it. Might also be great for base moves.
