Randomise Garrison location spawns (maybe a bit more if possible)

[ScarletFox]

I realise they already are sort of random. 
However, on AU Scourge they tend to pretty much spawn in the South at the same 4-5 spots.
There are players who have bases close by to where all the know spawn spots are, and pretty much 'camp' the garrison as soon as it appears.
It would be cool if the garrison spawned randomly in all four directions as mid-map, even on ice-burgs.
I've observed players fly from one side of the map to the other, to arrive and the garrison has already been taken (by a 'camper' who has TP'd) literally within minutes of it spawning.
