The leveling isn't so fun when you've done it soooo many times ;_;
Now I know I don't beat Himeko, but I've leveled to
max level:2 rogues (one aussie server horde, 1 Zaknalols)
2 Belf Pallies (Cuddlewuddle and the one on EU I raided on)
1 Druid (Evale 1.0)
2 Priests (Realised I needed a dorf for fearward so started from scratch during BWL)
1/2 Hunter (Asmo EU and it was the end half)
1 Warrior (Horde)
1.5 Shamans (Evale 2.0 then Kval from lvl 40).
1/2 DK (they start at 58 so they don't count as full)
1.5 Warlock (1 full, the other is a 59 twink).
And then various others to like lvl 40
And I stilllll like doing it! The druid and priest were when that shit was hard, too, before there even was boomkin let alone a real feral. In my day we leveled uphill
both ways.
