Let me ask you this then, where can 25 points benefit you better than on your Warlord?
As far as the new 'dex goes, I fuckin' want that shit four months ago. I would completely settle on:
1) across the board lower points cost
2) access to Pyromancy
3) Tactical squads getting special/heavy weapons at 5 men strong
...and I'm sure a few other things, but those three things right there would make this space vampire happy. Aside from wishlisting units, psychic powers, chapter relics, and the like I could deal with those very simple tweaks. However, if we're talking wishlisting:
1) Mephy as Lord of War and an overhaul of his rules
2) Tycho gone, replaced with just about anything. Maybe Lemartez is in a Dreadnought now, really: anything.
3) Some points upgrade that makes Razorbacks assault vehicles (hey, I said WISHlisting), or a new vehicle maybe that's open-topped that we can jump out of
4) Access to Pyromancy - both here and before, because look at that table then look at your Libbynaught
5) Some wild new unit of battle brothers that have 'overcome' the Black Rage like Lemartez and now are the 0-1 Elites slot BA Veteran unit
6) Get rid of the 0-1 restriction on DC when you take a Reclusiarch as HQ, not just Astorath (and who the hell is that guy anyway?!)
and that's just the tip of the iceberg.
