Although the ult received linesman to be at shotgun levels, it feels underwhelming for an ability that’s on such a long cooldown and meant to be more powerful. It’s effectively just one blunderbuss shot that happens to get more pellets. After actually running it and noticing the spread, it does help clear horde to some degree, but getting more than 10 kills with it is quite rare, and considering that it’s an ult to only kill 10 trash-tier units that can be killed through any other means, it’s not a valuable pick in the slightest.
The most offending issue is the ult’s interaction with armour. My expectation when using an ult is some sort of power fantasy ability that can help change the situation. When I walk into a lot of storm vermin, I expect half of them to die when I shoot out a shotgun ability. The reality is disappointing where only the front storm vermin with die, and everyone else gets tickled.
I believe giving the shotgun more cleave through heavy linesman or tank would mitigate both of these disappointments by allowing it to kill more horde to build stacks of pellets as well as kill more armoured units or at least not be completely blocked by them.
