Hi, So i'm struggling a little soloing this challenge, People already know, projectile towers are a good choice for beating C2 maps in general as the Cyborks take out auras, nodes and traps. So with the no tower challenge, what exactly am i supposed to use to defend my lanes that's not a barricade? I am soloing this - so maybe that's my issue, but have heard its all solo-able? Am i missing something? Thanks :)
