I have only played a handful of 4v4 brit games cause I got stomped hard in each one, so I voted to buff them up
But seriously, I dont like the idea of making IS cost more. In a 1v1 Brits seem to lack capping power. If the IS cost more and get pushed off, I think brits will have a harder time than they already do in 1v1.
Seems like the stock IS needs buffed back up a little and maybe reduce the bren upgrade output so they are not terminator blobs late game?
Just a dummies two cents.
