T4 are you serious?
The range on this thing is absolutely sick and it suppresses everything that comes near it. Yes I'm serious. Is it mobile? No. What is mobile? A kubel.
Valid in the first 5 mins? Try and use your kubel a bit more carefully then.
because you can move the T4 building from spot to spot, where you need suppression

this thread is about a non
doctrinal, mobile MG to suppress inf, blobs on the front.
And even if you micro your kubel and use it carefully, it dies between the early and mid game anyway.(pathing, focus fire etc.)
