Wait, they didn't change the minimum level of the zones, if it stays like that, we'll be forced to do some zones, and unable to begin by the zone we want on each expansion for example... it's strange.
If I lv60 I can only do the beginning zone of Outland and LK for a few level for example, I can't go to the one I want, meaning I'll always do the same first few quests on alts we already do today if it stays like that. Hope they'll change that quickly.
To everybody crying about the leveling speed:
A quest in Westfall currently rewards far less experience than a quest in Eastern Plaguelands because of the obvious level discrepancy between those two zones. For zone scaling to work, the experience rewarded by quests must also scale and change as you progress in levels.
Until somebody mentions how much experience a quest rewards, I'm not going to worry about the amount of experience required to level. It may not have even changed much. Remember, these are datamined numbers that may be misinterpreted.
If somebody can actually time themselves going from 1-20 on live and compare that to 1-20 on 7.3.5 using the same class and under the same circumstances, then we can have a discussion. Until that point, whining about a datamined number will do nothing for you.
It's too soon to say whether or not increase experience means longer leveling period. I doubt Blizzard would intentionally make the game take longer to level up -- that would be pretty foolish. It's probably related to zone changes as others have already mentioned. I'll withhold judgement until I get a chance to test it.
Saurfang finally gets a model worthy of his unbridled badassery.
"Many Ulduar achievements have been moved to Feat of Strength, with a new non 10/25 player version replacing them." Well, RIP for the loss of a good chunk (roughly 1,100) of achievement points!
All you got to do is level with white vendor armor & weapon if you don't want braindead easy fast leveling. As a matter of fact, making the game more challenging and slower for yourself is pretty ridiculously easy. To be honest, it doesn't sound like you want the game slower for you. Sounds like you want the game slower for everyone else who you don't speak for.
