At 60 I had no mount nor money to buy all my spells

You level insanely fast, 60 in 2,5 days played or faster

"WTFpwning" will still be fun after 50

Have a look for a leaderless setup on these forums, that cuts out your middle man and is very flexible. (It uses Keyclone instead of hotkeynet, sorry)

I still turn in quests by just open the Q window on each toon and then having my main select the options (Multiboxer addon makes your alts pick the same chat options as your main)
