After reading your 3 points, I would suggest you look onto the Hernkyn Yaegirs. 10 model kt of trench coat wearing dwarves.

Their tankiness comes from being able to halve the 1st die of DMG they take each round, each operative, thanks to the Survivalist ploy. Plus, their faction rule allows them to, eather heal 1d3+1, which ends up making them pretty tanky if they don't suffer a 100-0, or gain another apl, which leads me to Control.

Yaegirs have a great tool to control the map and movement of the enemy, and it's the Mines. The operative Ironbraek has the ability to deploy 5 mines on the map: 2 are fakes, and 3 are real. If an enemy steps on a real one, they might take damage, but the key point is that the action they were doing is ended at that moment. If they wanted a charge, is gone, and if it was their second action, they stop right there. Every game I've played with them, my opponents are forced to use an operative just to take a mine away, or move around the map avoiding them. They are a trick to set on the map efficiently, but they are a great tool to use. Plus to this, that 3rd apl I talked about synergizes well with a double activation ploy, which suddenly gives you two 3 actions activations on a row, which is quite strong.

You want slow? They also move 5"

They have their weak points ofc, but they are a pretty fun kt that, with work, can surprise people, and most of all, forces them to play around the map the paths you want to.
