This is the guy that got rammed in the video.
If that's not a competent player, then you're garbage by your own definition.
1) And helpinghans was constantly parking on his own teller mines and had them blown up under his own vehicles.
Top players are players who are highest at the ladder, not omnipotent gods of the game who can never do wrong.
2) If you are at situation where losing a heavy tank could make or break it for you, WHY ARE YOU LEADING WITH IT? Having scout/sweeper infantry in front of it is a basic thing, unless its a vehicle you won't regret much losing, yet at presented clip none were present. Huge mistake was made, top 10 players also do them, just less frequently then you or me.
