Just started playing this I suck really bad, been using the T1 fully upgraded still only got 1 kill out of all my games. What tank should I get next? A medium, SPG, or a TD? I cant get heavy yet, so those are my only choices. Also why is the T18 Tank destroyer cheaper than the T2 medium tank.
I haven't played anything US, but I have shot at plenty of them ^_^
The T1 is pretty meh, but the M6 isn't bad and the T29 seems to be pretty good. The T1 is a really big brick of a target and US tanks in general have crappy hull armor (but good turret armor), so keep your front to the enemy and try to fire while peeking over hills.
Also, kills don't mean much. You get exp based on your overall damage done, not your killcount. A high killcount means you are one or a combination of a few things: a "kill stealer," lucky, and/or seriously outclassing everyone and one-shotting everything in sight. I once had a 9 kill game, but I was an SU 26 with a 122mm howitzer and the heaviest thing on the field was a panzer III. It was amusing, but I didn't get much more money or experience than I did in games where I got one kill but was plinking away at KVs the entire time.
If you want to get better, try being a TD for a while. You'll get a lot better, die nonstop, or possibly both. If you need a break from the frustration, get an SU 26 (russian arty, t3). Arty is relatively stress-free, and the 26 has a turret that makes changing targets painless. Most games as a su26 basically boil down to you playing whack-a-mole on anything that gets spotted, and its high-end gun (with the 150credit/shot ammo) will keep up with T1s and KVs pretty well.
