I finally hit the button to turn off "Assault" maps. It seems like every time I hop in a TD I end up with assaulting a base. I try to hang back and support, but waiting for a battle to unfold while watching no concerted effort from my team is really hard. I tend to die while not making xp nor silver.
I'm pretty much running the SU100 and T25at to grind for xp. I only have 300,000 xp to goto unlock the T92 as well
