Been playing my VK2801 a ton, love it with the new physics. One thing I've really noticed is how often with the newest MM I get pulled into matches where I'm up against tier 8/9/10.
This is pretty fun, especially with the speed advantage of the 2801, but one thing that stands out is the 'Fail Team' effect.
Essentially, if my team fails there is little I can do to to turn the tide...where in some lower tier battles I can play poorly and still have the team win...not so much with the Tier 5 scout.
Still running 54% with it though.
