Just toss the lore and IP right out the window. Because The Lord of the Rings would be that much cooler if Gandalf had thrown fireballs and lightning bolts. It is a neat little class, but what is it doing in The Lord of the Rings Online™?
This is based entirely on the appearance and what the character is doing. At level 8, I cannot say much about the class as gameplay (although fun so far), but I am already throwing lightning, summoning fire, and freezing things. Pointing a rock at the enemy and gesturing emphatically seems to be key here. I also back-hand monsters instead of carrying a weapon.
The graphics have been tuned down from the beta Sith lords, a visual so out of place in Tolkien that they sent the community manager to say it was okay because the promotional screenshots were not representative of actual gameplay. Despite that, you start every fight with a gout of flame, and at level 6 you can summon a bolt of lightning to strike your foes (underground, sir dwarf), in addition to the two electrical attacks you already have. They also summon shoulder-high healing rocks. I wish I could tell you about their higher level flashiness, but the only time I have grouped with one, we also had a Loremaster, so there were competing fireworks.
My Hunter had wondered why Eregion looked like it was having flashing lights all the time: there was a Runekeeper one hill over. Seriously, I thought the in-game lighting might have been broken in part of the zone.
