It is worth keeping in mind however that numerous rumors point to new Daemon books coming out for pre-order in late Feb. (Hastings says so!)
I would bet eating my hat that Bloodcrushers for example will become true 'Cavalry' unit type, just like the
CSM's Jugger did. That alone will seriously ramp-up their abilities since they'd then be just as fast as those Fiends in getting to grips with opponents.
For now I'd say wait and see what changes Tzeentch has planned for us...
Odds are pretty good for example that our Troops will all see pts reductions, while alot of our big hitters could likely be gaining new special rules and some pts adjustments to follow. (ie: Princes will almost certainly go up in pts, while I'd expect the Soul Grinder to gain either 'It Will Not Die!' or something very similar since it is a "true" daemon engine)
Besides, new books also mean shiny new toys!
