So, a couple of things have likely gone under the radar with the advent of sweeping changes to undead factions. Now that many of their tools are more or less in line with what you should expect from them there is a lot to be said, however Vampire Counts are lagging behind their sea salty brethren. Now, while neither of these factions are bad, they do say that seasoned players are usually better than other ones...
This is a proposition to make the Vampire Counts playstyle more dynamic and less reliant on "I take big monster and cycle charge you until your big monster dies, then I cycle charge infantry" or "Joke's on you, I have a mortis engine still so I win!"
Attrition playstyles are bolstered by healing and damage over time...but you know what else can do it? Pssst. Buffs and debuffs
Augmenting Auras such as Archaon's Crown of Domination and the Grail Relique's Icon of Devotion are activated at 55m making them pretty useful tools for supporting a front line without being too endangered. Now, for vampire counts this is of course a little bit different since their units are all functionally unbreakable meaning that penetrating a formation can be difficult, however I think this would be a step in making augment auras more useful.
Malagor the Dark Omen- Icons of Villification increased range from 40m to 55m
Corpse Cart- all auras increased from 40m to 55m
-things that shouldn't have the aura size increased
anything that causes HP drain or deals damage
