So here is the deal. We can talk about it as much as we want to, but the truth is that these tanks will never, ever read those forums. They just prefer to ignore anyone that wants to help. I have encountered two tanks in this game that were doing nothing else but spamming only RoH. Not comboed. Just RoH all the time. The problem was that they did not have any idea how the combo system works.

What you say (the trial for tanks) is not good idea. These tanks who want to learn will learn. These who don't will just skip the tutorial instantly without even reading anything. And even if they don't - do you really think that these tanks will be any good in the future?
