I've a few alts. Actually, I have enough alts that my Guildmaster has chided me for trying to be a one-man Guild. I often create the alts to help friends level, but there's only so many hours in the day -- I can't really make sure every single alt has valid gear for their level. I'd like to be more effective on level-appropriate runs, but usually these guys are just tramping along on whatever quest gear happens to be available.
The new Binds to Account gear is going to be incredibly helpful with that issue. You purchase these items with dungeon tokens (like Badges of Justice), but you can pass them around between characters even after use. (You just can't give them to other account-holders, they're only good for your characters.) Tigole calls these Heirloom items.
The really cool thing about them, however, is that they scale with level. You can pick up the Dignified Headmaster's Charge, and use it at level 80. At that level, it gives you 93 Stamina. When your 80 gets an upgrade, pass the Charge down to your level 1 Warlock. For that guy, it'll give only 2 Stamina.
The other neat factor about these Heirloom items is that their models are based off beloved old world items. The Dignified Headmaster's Charge, for example, is an item model familiar to those who farmed Darkmaster Gandling. So, we get to see some of the cooler looking items back in play again.
Yeah, I'm pretty excited about this.
