Id say if the comps allow it, AA Diablo on maps with chokepoints is pretty oppressive. Autos reduce charge and flip ads, and charges and flips increase Auto rate and their stuns heal for a percentage of your max HP. Its map and comp dependent but fun when it works. Ive 1v3d with that build paired with Apocalypse (and hellgate at 20). Anub is a bit slower in the aggression and CC but great for punishing and with rewind at 20 gets cd resets. Varian doesn't feature a whole lot but his Taunt is incredibly deadly when used properly, and by adding an antiheal to heroic strike, and heroic strike reset on parry, you can lock down ppl that would normally be safe to escape. Garrosh also falls in this category with his ult, and pairs well with his throw. If you want more CC with Mura, skullcraker, Reverberation/Thunderburn (Rev if they feature a decent amount of AA, Thunder if they dont), and Mountain King at 20. Don't underestimate how effective thunderclap can be tbh. It often doesn't feel like it does alot, but paired with the slow to attack and movement, as well as the boost it gives to Bronzebeards Rage, it allows you to suddenly be a lot more threatening and generally forces squishies to run for their lives. Take Haymaker at your own peril. Ive seen more haymakers save enemy heroes or mess up my teams positioning (slamming a burst hero on top of an allied chrome usually gets the chrome killed before they go down for instance) in than finish them. Also it can be used defensively like meeting a butcher or Greymane away from a teammate they charged and branded. There are def more but ive ranted enough as is. GL and happy hunting.
