Terrain Building

Whoever designed the terrain and where the hitbox for certain features starts and ends is either a potato or did his/her job over night.

Theres so many rocks and buildings that have hitboxes that extend far beyond the visual model of the building. You can even shoot through some terrain features.

And it's not just buildings, there's certain parts of the ground which you can't shoot through even though when you hover over an enemy tank you can see the red outline, which should indicate that you have a clear shot, and then your shell proceeds to hit a very solid piece of air, which is the ground's hitbox.

Get your priorities right war gaming. Stop focusing on new broken tanks to introduce to the game and focus on balance and game quality updates. There's been one single balance patch in this entire year, which for a game that has as many vehicles as WoT is absolutely pathetic.
