Why should I help others if I get no extra dkp?

It almost sounds like you're asking for special privileges because you have more characters in the raid. Which I would definitely say is a bad idea.

The rule i follow when play with all my characters in a raid:
"All my characters will be treated like any other player in the raid. The only difference is i can choose who gets what loot. For instance say i have 4 characters but only 3 need the item that drop, i get 3 rolls but last in my chain of command wins, i want loot on the 2nd since my first already has the item." However the loot on character i want thing doesn't need to be said now since you can trade bop items now to fellow raid members.

Zal that's what I'd do if I was in charge.
But I like to pre-empt any resistance by saying up front that I'll only do two rolls: One for my main and one for my alts (until everyone in the raid's gotten somethin who wants somethin')
Now that stuff is tradeable, it's nunya what I do with it once I win either.

Well (for WoW and the new 2 hours trading on loot) I'd say what's to stop 2 or more seperate people in a raid rolling on loot, and then giving it to the other person, just to increase the number of people rolling, and that /group's/ chance of getting the item.

There's no way for the rest of the guild to know if any of it's members are acting in their own interests in rolling on loot (unless everyone is armoried regularly to make sure they are using items they won), so why should they stop you from doing the same.

You getting 5 rolls on loot, and then giving it to whichever alt you want from that group who needs it, is no different from 5 players rolling on loot, and then giving it to whoever needs it behind the scenes (within class use rules for the item).
