This one, on the other hand.
No shit if I've done it 5 times I can do it 6 more times. And ya know, if the time comes and that's the way it is, then that's how I'll do it. However, if they allow alts to get it sooner, I'll be right in line with every one else to get it. (Unless they make it comically cost prohibitive or something stupid)
That being said, are you honestly implying that after leveling to level cap once, twice, 5 times, whatever, that there is any kind of danger or challenge? You already know the quests, you already know the efficient ways to do things. Doing it on foot is just slower due to travel times and working through some extra trash mobs. It isn't harder, just more tedious.
