Playing a new Luchs with no upgrades is humbling to say the least. Even the 37mm gun is not much fun and being taken out by T-46s is embarrasing.
Got an elite AT-1 which I am really enjoying; the 57mm is brilliant and the 76mm allows you to one shot. You're never up against something you can't hurt although everything can outmanouver you. So am really learning the ropes in a TD. Tier II is definately the funnest so far. russian artillary is fun although the first one is a big gun stuck on an MS-1!
