During my level 60 cap I:
-hit 10k hp
-soloed Strath, BRD and LBRS (didn't try Dire Maul)
-spent over 1200g on enchants
-Was MT for a full BWL run, just for old time's sake
-Repeatedly took down level 67 DK's (duels), never could get above a 64 preist/paladin.
-Was called a twink repeatedly
-Got kicked from a BWL raid for
loosing a roll on eternium ore.
During my level 70 cap I:
-MTed Kara
-lost all my level 60 epic enchants and got sucked back down to 10khp (11.3k now)
-Soloed Ramparts and Blood furnace
-Sufficiently established my reputation to the point that I got a reserved MT spot for Naxx and Uldaur.
-Have been forbidden from respeccing to holy because my guild and friends want
me as MT.
-Got Baron Rivendare's Deathcharger my first solo of Strath being level 70. (people hate me for this, /sorry Sab. sorry adorah)
-Got my Black War Bear (everyone has one of those)
-My group wiped on the Blood Elf brat in Magister's Terrace when he was at 30% [edit: scratch that, 20%]; I took care of the rest... that was fun.
-Soloed Eranikus in ST WITHOUT clearing any dragons (except the two flying ones in the room just before his)... for a total of one Eranikus, two flying dragons and 2 million other dragonkin on me.
-MTed Magtheridon
I have only been at my level 70 cap for about a week; I have yet to see what damage I can do in pre-BC raids (solo).
Next, I want to get my brother's Horde guild together and organize a 40-man level 20 raid against.... me. Maybe level 10

nah, 20. I don't know, how much do you think one could take?
