Leveling Route?

Hello, i've been playing on Icecrown for a few weeks now and was wondering if an experienced leveler on this server could tell me the best leveling route for alliance? My first character was a warrior that i just planned on getting to lvl 55 to make a DK and it took me 13 and 1/2 hours to get to lvl 55 and i feel like that must be super slow, sure a bit of that is probably afk and being dead to horde in stranglethorn, but i was just wondering if someone out there has a good route, seems like most of the topics about leveling on icecrown are either unfinished or have been deleted.

thanks in advance if you do :)

Hii. Download carbonate addon. It tells u on the map which is the best place to level. And once u reach about level 70 and go to northerend. U will find more horde players. Gotta deal with that. Sorry. But download the addon... it helps a lot in questing.
