personally i want this to be 1x. yeah i don't consider leveling in itself (grinding the mobs) to be the best part of the game, and i've gone through it before. but at the same time, my interest is BLIZZLIKE - and so is yours since you are here posting, right?
there's a lot to be said for long time rivalries formed through people you meet while leveling, and the longer this takes, the better, i reckon.
let's say some guy kills you. he just set you back a considerable amount of time - and possibly wounded your pride. the thing i enjoyed the most in retail vanilla was the situations that came out of this kind of confrontation. i was constantly on the look-out for these players (vanas kos here we go), and killing them back was sweeter than apple pie - dying to them was so frustrating it actually was rageful :lol: similarly, you could meet allies doing this and make valuable friends. but the game wasn't just in the game, there was the forum trolling and shit shooting on the forums. i hope the mods won't be strict, drama is half the name of the game.
imo what happens when you increase the rates, is the devaluing of the entire world map until near-max and max level areas. nobody will have any practical reason aside from gathering to be in these "non essential areas".
in a way, warsong is a perfect example for people who want something for nothing - fast 60, poorly scripted loot piñata bosses. i don't know, i can't see the upside to high rates. it damages the idea of blizzlike and is off-putting to people that are committed to playing the game the way it was. if people can't be bothered because of 1x, i don't think they enjoy vanilla as much as they seem to think.
if population doesn't increase to satisfaction though, i can see my opinion changing. after all, high rate wouldn't be the end of the world - it just wouldn't be blizzlike... then again, it can be excused as long as the well scripted content is followed side by side with COMPETENT and FAIR staff unlike that monkey slav athairne and his ilk
