Here's an idea that came to me and I'm curious what you all think of it.
Raid Timer Reset Token:
This token allows you to reset one raid timer of your choice. With a reset token in your inventory, simply talk to the quest giver for the raid and there'll be an option to use the token. A reset token can only be used once every 3 days.
With the 3 day period it would in no way allow for ransacking of raids, but would simply allow someone to have a second go at any raid he/she so pleases.
It would be a DDO store item and perhaps could be a rare drop like experience pots and such.
