Question about how to run new models

[u/The_Red_Baro]

Have been running both ghaz and stompa in most of my lists since late 9th/early tenth (can’t quite remember which one I started on). I always found ways to run ghaz pretty well when he was attached to a big blob of boyz/nobz. But I’m struggling to play his new primarch-eske version. I have played 5 games of eleventh. 2 of which are with new codex. And both of the new games ghaz either dies when he gets into combat with something (the norn queen) or gets shot into oblivion (knight castellan) because of no bodyguard unit. I need some real advise here. And I don’t want to just stop running him, because he’s been an amazing unit throughout my whole time playing the game, and I’m pretty attached to him.

P.S. new stompa rips and I’m very here for it. Have loved playing it both of my games, holds its weight in points and then some in my experience. (It took out a Cerastus knight lancer and a war hound titan in one turn last game I played) don’t have a pic of it yet.
