I dunno...there are a lot of interesting ways to make truly HORRIBLY powerful characters in the new codex's. And they seem to be trying to one-up each other, in that each codex is more potentially cheesy than the last.
Space Wolves can make a BIZARRELY overpowered Wolf Lord, and the new Blood Angels SCARE me, frankly, with what I've seen. Just as an experiment, derived from something Chrome cooked up:
Space Wolf Lord, on thunderwolf, with Saga of the Bear, Runic Armor, and Wolftooth Necklace, and carrying Frost Weapon and Storm Shield.
270 pts, assaults 12 inches, is immune to instant death, ignores wounds from psychic attacks on a 5+, hits on 3+ in close combat, always, and carries a power weapon, with the stat-line
WS 6 BS 5 S 6 T 5 Wo 3 I 5 A 5 Ld 10 Sv 2+/3+
Now, admittedly, he costs a bit at 265 pts...but that's still just a generic Wolf Lord, and not a special character...
Apart from that SEVERE diviation from the subject...the stuff is VERY lovely, and if I played 'Nids, I'd WANT. However, since I DON'T...all I can say is I am IMPRESSED, I am.
