There are two opinions on TD's:
1. People don't know how to use them and cry about getting owned.
2. People that look at the stats and know that something isn't quite right.
I fall into the latter category. Compared to tanks TD's have the same if not weaker guns, weaker armor, less mobility, more restricted view ranges, and are hideously expensive(esp the Ruskies) compared to the equivalent level of tank.
The very slight accuracy bonus just doesn't cut it against the major negatives, which almost seem to get worse as you get up the tree.
Yes you can do well, on certain maps and certain makeups, but if you deviate from that you're going to have a tough time. Especially in T3/4, you can't do any serious damage to anyone but light tanks and will get SPG'd if you reveal. Some of the maps just don't have a lot of good spots. Plus most of the tanks you will encounter can out range you.
Every single time I spot a JagdPanther, JagdTiger or Ferdinand when I'm in my T-34-85... the word "shit" repeats in my head over and over again because the players that have gotten that high seem to be extremely effective. It's like 'panic stations' as they will often track me in one shot and you're desperate for the repairs to happen or some artillery to smash their sniper cannon.
In mid-end matches where T4 to T7 tanks roam, I find Tank Destroyers to be a formidable opponent which I rarely best although 1v1 against anything up to and including the JagdPanther is a victory for me (unless I'm surprise attacked and tracked/so badly injured I'm taken out in the initial shot).
They don't need tweaking on the mid-end. Maybe they do need a low end boost or a high end boost though I can't tell because I was so awful in my AT-1 and I don't have a KV/IS or equivalent to compare the higher end TD's.
Oh I know, it just isn't a capable enough tank to scout through what they match it up against. Its speed isn't THAT great and it really has poor maneuverability.
The BT-7 is an awkward scout vehicle. Rather nippy but doesn't like turning very much but you need to get used to it. The A-20 is lightning fast, the fastest in the game, and doesn't turn very well either.
Both are awkward and unwieldy until you get used to them and you will be fine. Dodging and weaving in and out of enemy formations and then curse it's poor turning ability when you get up close and personal.
As far as scouts go, I hate the BT-22/BT-7, A-20 and Leopard because they are just so darn awkward to hit
Sweet! Just unlocked T-43
Nice work... I just unlocked the 100mm gun on my T-34-85. Finding it to be very awkward to adjust to such a long reload time and not that impressed with the damage so far though I haven't had too much chance to use it effectively. Took a KV-3 down to 50% with two shots to it's frontal armour which was quite nice to see.
