My first post!
I just reached Rank 15, and since I've been hearing about all these no-wall strategies using the Commander Hero, I figured I might as well give it a shot.
...and I died in the first ten minutes. On Easy Mode. Whoop-de-doo.
So I'm clearly missing something. Could anyone give me some pointers on winning with a no-wall strategy, or at least using the Commander properly? He seems like such a fun hero, and I'd hate to miss out on using him well.
