Alliance of Sorcerers argues that real spellcasters don't wiggle so much when casting spells. Castanics don't care.

All I can think of while watching the trailer is that their armor must be very, very uncomfortable. That being said, TERA has released a brand new trailer that really redefines what it means to be a "reveal trailer." This new trailer lets players see various Castanics in action while showcasing their uber-sultry outfits. While not quite NSFW material, maybe you should close the door before watching. Just a suggestion.
