I saw no one had the GUTS to go ALL IN on BOOMS and fully meet the glorious Rumbler's potential. Shame on you brogryn, but I will forgive you in the Emperah's name.
This build is an absolute meme (BIGGEST BOOM GOOD), but it turns out to do stupid amounts of damage when executed properly in Auric Maelstroms as well.
There are quite a few oddities to playing it, such as using your ultimate before building up blaze away stacks when fighting large groups or monsters. Also, you have to spam left click to keep your blaze away stacks up or if you're too slow a lucky bullet proc will remove the buff.
But it's all worth it because when things get really hairy and the enemies are piling up that's when it's your time to shine with explosions everywhere you like. Throw your enemies around like toys with your powered up maul and then finish them off with a quick nade from the rumbler. You really can't go wrong with BOOMS, when you're in doubt, add more BOOMS
You're welcome, now go blow up some heretics for the Emperah!
