I have been playing this hero since before the wipe and I have done trial and error and I find that this works best.

Let me know there are some situational things, but this is HAMMER CARRY.

if you can get your team to understand to protect you late game you can push lanes down hard. I have played a bunch of games and I am over 70% with this build with this hero.

level 1 ambush or advance artillery
level 4 healing is strong because he can tank some damage
Level 7 I get thrusters but I can see if you want healing. I like it because I can get places twice as fast and actually catch up to ppl to kill escaping foes
level 10 This ability can help kill escaping foes when you can move from siege mode
level 13 I get the wall Barricade only if I am behind if not 80% first strike
level 17 you can move while you are in siege mode
level 20 you know of course CONSTANT LANE PUSH

TRY THIS BUILD LEAVE A COMMENT LET ME KNOW WHAT YOU THINK!!!
