This build seems to be very strong once you gain your heroic, as you can surge past a player, activate blaze, then stun with hammer (pushing player back toward your team). I like this build more than some of the tanky builds with Cho; the survivability seems comparable to other builds but with this build, he's extremely mobile (and fun!). *This build conceptually makes Cho similar to ETC with the stun and knock back. If you enjoy ETC, I think you'll enjoy this build.
