Based on Tobold's World of Warcraft Personal Status Report I decided to do a similar one.
My only problem is I have much more alts. So sit back, and enjoy the fun/misfortune of an Altoholic.
I currently have seven level 80 characters, a Warrior close to 80 and a mage in the low 60s.
My Priest is my main progression raider. My paladin is my other non-progression raider. My other 80s, are used to fill raid holes, or assist guild members with whatever they need help with. My Hunter and Rogue are not even geared for heroics yet.
My Priest's gear is good - she just needs Frost emblems for her heal set, and more Triumph for her Shadow set. Paladin has a great tank set, but could use a shield upgrade. Her heal set also needs some Triumph badge loving.
The Druid has heal set from Triumph badges, but her tank set needs work. Death Knight's both sets (Tank and DPS) needs Triumph upgrades, similar the Shammie. All of these three can fill both their main and off-spec roles in non-progression raids.
My Hunter and Rogue just both have some BOE new level 80 epics, and quested blue/green gear. My Warrior will have the same when she hit 80 (which should be in the next couple of weeks). I spend over 1,200 gold last night to have a guild blacksmith craft some of the Titansteel BOE epics for her (as he needed the skill-ups). Mage is too far of to really have a good idea of how her level 80 gear will look.
So what's my plans? Previously I thought to get Loremaster on at least on of my characters, but that lost its appeal. I love questing as my army of alts demonstrate... So I think, once all of them are 80, is to start by having all of them complete all the Northrend quests for the zone quests achievements. That should provide me with enough gold in the bank for Cataclysm (and I might even get epic flying on more characters).
Other than that - just keep queuing in either Dungeon Finder or LookingForRaid to collect emblems for T9 upgrades.
