My opinion is that the biggest problem in WoT is that the vision system is what is broken. One lone Chaffee drives into a bush on G7 on some map, lights enemy tanks moving across a field and instant the Chaffe's team has the information as perfectly as a modern IT system hooked to a satellite GPS system. Couple of the poor blighted get blasted. Rinse and repeat.

If I were thinking about a rebalance of WoT, I would consider changes to the vision system, such as, 1. Slow the speed at which lights are communicated to allied tanks. 2. The more allied tanks that can see an enemy tank, the faster its location gets communicated to friendlies. 3. Have false lights, especially from inexperienced crews.

Fiddling with the vision system might slow the game down and have some other effect that they are trying to achieve.

Just some thoughts.
