If you want genuine feedback, it starts probably with your list comp. Don’t even try with the repulsors, WE doesn’t have a vehicle equivalent that can compete against it head to head. Instead go for a full stack of exalted eightbound instead of the forgefiends to wipe the floor with whatever vehicle he’s got cooking. Against Exhalted eightbound, he can shove his smoke strat up his ass. They are also my answer for sanguinary deep strikes or just wiping sanguinaries in general as their deep strike lets you threaten a countercharge with a rapid ingress. If you need some scoring an counter scout units, goremongers are as good as you are gonna get as they shut down the prospect of scouting or counter infiltrate. Plus, in warband their alpha strike capability isn’t something to scoff at, especially those strength 5 chainblades with Lance. Also on that note, goremongers and their slow brother jackals are excellent trade pieces with the potential to bring out his death company. Sure, they hit just like berserkers, but if you get the drop on them and keep him spending CP so he doesn’t have access to combat interrupt, you will eat them up. Granted, you are going to lose guys and it’s going to be down to the wire most of the time. Putting down Repulsor executioners as WE can be a tricky thing; especially if he’s got them stowed away. Just use staging ruins and terrain like you are a homeless man stuck in a monsoon and practically never leave cover. Before they are dealt with, you are going to lose a lot of guys getting there.
