They couldn't have made it any worse.
The new rebalance, as they call it, is not a rebalance at all, just changing numbers.
Changed the hp, but changed the alpha dmg as well, didn't make tanks any more survivable at all.
Removing lots of low tiers achieved nothing.
For example, right now you can research 4 tanks from the Tiger P, the Tiger 1, VK 100.01P, VK 45.02A and the Ferdinand. So that's 4 lines you can split into from tier 7.
From the new tech tree, you'll have to play 3 tier 5s, 3 tier 6s, 3 tier 7s and only then you will split into another tier 8. Didn't make it easier at all.
And claiming that people get lost in the current arrows and stuff, well that's just incompetent design of the tech tree, or a certain player's incompetence to follow the line.
