Class roles in Velious?

[HeallunRumblebelly]

To answer your question about velious raid roles

Warriors tank (main and ramp generally)
Clerics heal
shm / dru / enc buff (shm also can do some decent healing) -- really depends what version of mobs we get for places like tov / kael depending on their charmability but they're all unmezz D=
SKs don't do !@#$ but the ocassional inc pickup and light drake work in ToV
Paladin casts brells, note singular :P
Mage / Rogues / Wizards / Monks dps (monk also pulls)
Bard is manabot for CLR due to lengthiness of encounters
Necro pumps CLR mana

As far as velious raiding goes, wizard / rogue / CLR / 1-2 warriors who don't ragequit will be what decides whether your guild progresses or stagnates (assuming you get the encounters from the other guilds D=)
