Am i the only one who seems to realize that to equalize against a 40 fuel unit, (the land Mattress) one needs to spend 140 fuel on a brummbar as a bit ridiculous. I agree that it works. But its basically a good summary of balance in this game atm...
brummbarr costs 150 fuel fyi. yes it is t4 but its the most effective counter to blobs. Also piat blobs arent cheap. keep moving your mgs and hide some mortars nearby to keep him moving. Point is, don't try to out DPS the blobs with infantry. Use support weapons like mgs and mortars. Keep them in good spots and behind green cover (use pios to make sandbags). Once you can afford it, brummbarr is a good option or pwerfer.
