And with all that, how was your weekly WoW playtime?
If you ask me, the problem was not the absence of flight paths and the presence of group quests.
It is just that the leveling flow didn't make any sense at all and you had to rely on a leveling guide to be more or less quick. (All hail Jame's horde leveling guide
) Sure, as a first experience it was great, but after a couple of days, not so much. I won't even mention the fact that the quests were not numerous enough and you had to put in copious grinding sessions in between (hi to the harpies in Thousand needles, trolls in Hinterlands, BEs in Azhara and skeletons in western plaguelands, I don't miss you).
Also, for new players, some mobs were way too hard right from the start on, especially given the fact that most classes/specs were broken.
And who on Earth are you to decide who is suited to what? And frankly, there is no fun in dying repeatedly to lvl 4 mobs in the starting zone.
I'll tell you even more: back in my raiding guilds, most players hated leveling with a passion. They wanted to raid. Should they be removed from MMORPGs too, by that logic?
Because people who did already enjoy that were a tiny minority, and you don't make decisions based on an opinion of a minority. That is even before financial considerations.
Because there was nothing fun into hoofing your way through a zone?
As for elite mobs, there is nothing wrong with having them, but having elite zones (e.g. the troll city in Hinterlands) was frustrating when you couldn't find a group (which on my realm was 95% of the time).
