For those who may not know, GRIND was what you did in vanilla. You would take a gathering profession -or two- and grind on mobs/areas for hours as to afford mount and consumable and turn a profit. From the early copper/linen/wool farming to the late 30's Earth Elemental to 40'sh and then more mats -Felcloth/Mooncloth- and so on.
While people expect to 'grind' those who have not experienced the amount of it will not be too happy.
Predictions:
How do you think many/most of today's gamers will take the amount of grind needed in Vanilla?
