Though I have successfully employed both, the comfort of one free will per turn, a la wizard style, is my preferred method of casting. Who doesnt want free will? However, when you *really* need to land a spell, there is something to be said for the wraith style. The confidence that comes with throwing 6 dice to ensure you successfully cast a spell and knowing you still have 10 will draw upon is nice as well.

I think that, as units, the Ringwraiths are better. Even without magic, they have the option to ride a fell beast, giving them a killing power that wizards don't have. Plus, a couple of sap will from a wraith will make any wizard into a very expensive one attack model, while the wraith itself would still have enough will to be a thorn in your side.

Radagast on Sleigh says hi. He can just Panic Steed a Fell Beast away. His 5 attacks + Sebastian are amazing. His spell list may not have Sorcerous Blast, but it is incredibly awesome to Immobilise a big hero, charge in, win and have 12 dice to wound.

That's an interesting question. Personally I'm a Ringwraith guy, they're reliable, they're flexible, and they can be quite cheap. I do feel safer with the 6+1 of most wizards than I do with a more finite amount, but like you guys said, when you really need to get that spell off, sometimes you just have to 6 dice it.

Having said that, for me the two most powerful spells in the game are Fury and Paralyze, both of which come from 6>will models. Wherever that leaves me, it leaves me.

Basically yeah she's super dominant.

However, New Galadriel strenght is also her weakness. She cannot lead troops, which is always bad and she is basically useless when Nazgul are not around. If the opponent has a Mumak or a monster, Galadriel cannot stop it.
A wizard is not as effective when against Nazgul (but I have to say, both Saruman amazing range and Raddy's cloak are incredibly good to immobilize them from a save spot and forcing them to give up will point even in early turns) but a wizard is more effective against anything else.
