No grind in vanilla? Your rose tinted glasses are beet red...
On active servers you ground out pvp (mostly AV) for 40+ hours a week and still probably wouldn't hit high warlord/grand marshall.
It would take a couple weeks (or mind numbing grind sessions) to take factions from hated to exalted. Now you get honored just for doing all the quest in the zone.
Seriously, if you think the grind is worse than vanilla you've repressed a lot of bad memories or didn't play much at 60.
