I'd like to offer some counter arguements for the undead armies, since before I played ogres those were my mains
Everyone saying that raising spam is gone and core troops have low init in the VC book should redesign their Vampire characters. Vampires can take the lore of light (necromancers can't, and should be the only guys spamming) which offers spells that grant WS 10 Init 10 and ASF. There is a crown in the VC book that allows the vampire to pass his WS to other units, meaning you could have two WS 10 units for one spell. Corpse carts granting ASF with high init means re-rolling graveguard you can raise from the dead
Vampires are no longer the spam summon horde that they were, but they are still a almost top tier army. Having unlimited (theortically) unbreakable troops that can be buffed is great. I honestly feel only two factors stop VC from being top tier;
1) Death magic (lots of races get death magic) can be used to snipe the VC general for easy win. This means you have to invest in magic resistance/wardsave for your hero or risk losing the game by turn 2.
2) You can't beat a good lizardman player regardless of anything you do. He's going to spam the level 6 spell on 6 dice and wait for a bad miscast. Then he'll push it on your caster general and auto win. He can do this pretty reliabily by turn 3 unless you hide your general. If you do that, he's taken a 400 point character out of your army, and still is great.
Tomg Kings got a lot weaker then VC. I would argue they are just above Wood Elves in term of who got nailed the worse. The rule that wrecked them wasn't fear not autobreaking (this sucks, yes, but I never had many massive hordes in my TK list to begin with) but raher steadfast. My TK army, personally, had a strategy that revolved around skeleton archer blocks holding units in combat while bonegiants (With WD issue)/ Ushtabi/Chariots slamming the flanks for easy CR.
Fear was nice, but I usually won the combat by enough that I didn't worry about it. The new rules for stonethrowers...I'm not sure how I feel about them. Partials going away is awesome..4 large templates a turn mean that TK have an impressive shooting phase, probably right after Empire and Dwarves...and some skaven lists. I just miss dropping them on chaos warriors/knights and having them disappear I guess!
However, I've heard rumors that they are after Orcs and Goblins in terms of army book release. I believe it's either feburary or june next year...but that's warseer rumors
. Still, some of them were spot on for the 8th edition rules...
