Bonus roll system

a suggestion


As far as a know the only way to achieve high-end items, is by raiding (probably over and over and over) or buying the item on the housing market.
To incentivise players to keep going on those raids, i was thinking about a bonus roll system, this is how it would work:


Everytime someone contributes to killing a boss type monster, that person receives +5 to his bonus roll number (saved in db somwhere)
This bonus roll number accumulates up to a maximum, lets say 25 but can be whatever you choose.
When the loot roll window appears, there is now an extra button where the player can choose to turn in his accumulated bonus roll.
That number is then added to his roll for that 1 item.


Extra: there could be a visual added that shows how many people are bonus rolling on a certain item


As it currently stands the high end items will be hard, nearly impossible to get, this system wont put in more of these items into the world, but might reward players who really want to try and get their hands on one of those items without buying it.


(ps: i stil think some sort of currency system wouldn't be all that bad! but thats out-of-scope of this suggestion)
