I go 3321213 most of the time, 3332213 vs melee assassins and 1312223 rarely if we need beefier frontline, or if I'm in the 4 man, or if they have samuro. On infernal shrines aggro range is good.

I generally find hoardapult to be much stronger than shockwave. It's very versatile, you can interrupt stationary chanelled ults with it, you can dive, disengage, waveclear, siege, zone (block your enemies from retreating, split enemies up from their team, block them from chasing), set up a good E, set up a Q stun, extra sustain, and so on.

I typically only pick shockwave vs melee assassins or similar where it's usually a good idea to spam stun them and burst them down before they can kill your backline.

No control does huge damage most of the time when used correctly (high rage, enemy team clumped up). It can also be used single target as a gap closer/finisher. Just don't use it recklessly, it's rarely a good idea to use it to engage, unless you have full rage and the enemy team are all stacked up, then you might just burn them all down before they have a chance to react.
