Greetings, my fellow tankers and RibbleStripe!
RibbleStripe, I wanted to say a big thank you for the low tier re-balance that came in update 6.4.
That was super helpful for those eight low-tier collector vehicles that got buffed, and for that we are very grateful! There are still a good many tier II, III and IV collector tanks that have about 30% less damage per minute than the tech tree tier II, III, and IV tanks, though.
Last time I mentioned this topic I gave tier III as the example. Now I'll use tier II as the example.
All 7 tier II tech tree tanks (once again, this is base dpm, without any equipment)
LT vz. 38: 626 dpm
10TP: 698 dpm
Pz.Kpfw. 35(t): 545 dpm
BT-2: 698 dpm
M3 Stuart: 540 dpm
AMX 38: 643 dpm
Chi-Ni: 577 dpm
Average: 618 dpm
7 tier II collector tanks, for comparison (as usual, base dpm):
Cruiser Mk. 1: 449 dpm
D1: 400 dpm
AT-1: 430 dpm
Tetrarch: 462 dpm
UC 2-pdr: 417 dpm
T7 Car: 479 dpm
Vickers Medium Mk. 3: 449 dpm
Average: 440 dpm
I know balance is not only about damage per minute, but I definitely notice this about 30% difference
in dpm when I try to play my low tier collector tanks and when I look at them here on paper. Therefore, I do hope further careful consideration will be given to the balance of low tier vehicles.Thank you all for your time!

It's not the RNG, the MM, the diameter of your shell, the thickness of your armor, or the number of premium rounds you carry that counts ultimately; it's the courage in your heart, the calmness in your mind, the hope and faith you have in your team, and the way you use what's at your disposal that truly determines Victory.
