I'm fine with it, it promotes preservation and discourages blindly suicide-rushing into the enemy lines.
Hardly, as the videos illustrate I was rewarded for base rushing by having my stug remain intact while my opponent lost his tank trying to destroy a stug that was abandoned for the second time in 10 seconds!
The second video shows the same situation, rewarding the player that rushed right next to my base with my scout car.
Abandon is a joke and I think should be removed from the game.
