Open maps are dominated by T37s, backed up by a few Cromwells and very few Hellcats.
T37 is just broken, so good job to WG for introducing a broken Tier VI scout, a completely broken Tier VII scout and a Tier VIII scout with a 152mm gun because, why the fuck not?, why can't a light roll over 1k damage on a T95?.
Tier VI, competitive, is broken now, it wasn't when the KV-1S was around.
