If you can survive the struggle of leveling up your toon.. you are most likely to keep playing.. the leveling part is a killer for those "non retailers" but again.. doing lowlevel pvp is just some of what makes vanilla wow great..
and because theres no flying mounts we actually travel the world by foot or flightmasters
when you hit 60 and you think the hard grind is over.. .nope.. time to do more instances for lewt
expect newbs but also steamrolling groups with crap gear.
40 man sharing few epics in raids is great .. because when you finally get an item .. you really got an epic item that replaces your month old piece of blue.. and you are just HAPPY .. your day is made.. yay .. time to celebrate.. and tomorrow you go pvp to try your new strenght .. later that evening you can see that little extra dps on the dmgmeter beating your friend by a few digits .. it is worth it .. it is worth it all !
also when you have to spend days and days just to hit 60.. you are more likely to actually apriciate your char much more than if you can just rush to any level in a few hours taking 5-10 mobs a time with your eyes closed..
Blood, sweat and tears lies ahead !
But damn the cookie is not a lie
