I used to be apart of a 11/14 H guild before it fell apart(loot was not the reason it fell apart btw) and we never really had a loot system. Most of the Raid members who need it just work it out with each other and decide who it will most benefit the raid. We were all a friendly mature team so there was rarely any drama about loot. We don't even run with master loot unless we have a pug in the group. If your raiders are mature and determined enough then they can work it out without a loot system.
Loot council and all that nonsense are really only needed when you have a bunch of loot hungry raiders in your group.
