I have seen replays of players such as Voodoo and lappen sometimes upgrading mex's to t3 and then capping them after (on maps such as canis river). I always first get storage around all the t2 mex before taking them to t3 one at a time. When is it viable to just jump directly into t3 whil and then cap that mex, n even do that to multiple mex's rather then caping all fist? Not assuming there is a giant chunk of mass laying around to reclaim.
Is this method more efficient depending on what u wanna do or something?
