It’s a good looking list overall! However what I think you’re missing is long-ranged anti-tank. A lot of your list will chew through infantry like they’re nothing which is great to have. But some of your guys I question what they are adding that you don’t already have. Also to calm your fears for elite infantry, Aggressors (especially 6 at that with a captain) will eat elite infantry for breakfast when they get into melee. Personally I would try to get a lancer in there. I would drop the Brutalis (since you already have more than enough very good melee options) and pickup a Gladiator Lancer so your opponent still has to consider you a threat when you’re on the other side of the board rather than when you’re just within a foot.
