They are NOT cheating by exploiting "Flaws" in the maps, we call this community mountain goats, they dedicate their time to finding different/new positions on maps that are advantageous and hard to get to without a certain tank and teamwork.
They are not cheating, they have simply learned the game and how to play it, they are making the most of the game, it's not called cheating, it's called skill.
And yes, they PRACTICE is training rooms so they can use it in pubbie battles, it gives them good results! Just because you can't mountain goat but they can is no reason for WG to issue unreasonable Perma bans. The Whole goal of Mountain-goating is to give yourself an Unfair advantage over the enemy, you NEVER fight on fair terms with the enemy, it's called dying.
P.S Love that -68 Reputation, really makes me wonder
It is CHEATS just like the T-22 mission cheaters.
Unbalances the map big time, just b/c you can doesn't mean it is right.
