You know Odium manages a public server and plays daily, don't you? He has probably just done that many times before. It's surprising that you were surprised during a tournament battle. In the recent past tournament tankers knew everything about their armor and the enemy's too. In fact there are numerous spreadsheets, diagrams, and how-to screenshots with everything you wanted to know floating around in forum archives. But those were the good ol' days when battle night wasn't just a lazy pubby night.

And "in the recent past" FHT players knew armor and Ammunition things AGAINST tanks, NOT .50 cal...

And "in the recent past" maps were not crashing...
