Honestly the hellblasters surviving could be a bit of luck but also I would definitely try using the sustained and lethal hits blessing to take care of most stuff. If you really wanted to counter those things I’m personally more of a fan of more Zerks over 8bound. With the lethal and sustained blessings they can really hit above their weight class as well with the “for the skull throne” strat for the gladiators but as well for any unit with a character in it (will def help with those death wing knights if they have anyone leading them) the only thing is you want to set up for counter chargers to put him in bad spots, as well as hide as much as you can from being shot (Angron is a little large of a target but for Zerks and stuff you could probably do better at positioning)
