There is a separate forum post about that on the forums. Lots of support for that idea.
How to Go Forward in Rebalancing (Poll)
Re: How to Go Forward in Rebalancing (Poll)
I want this.
I can't count the number of times I've heard from more than one raid group that "It's [class] day I guess" when one class with 1-2 people in a 40-man raid somehow gets a tier piece at every boss that drops one while others that are starving for gear go for a month straight without even the chance to roll on a tier piece. That's one of the largest benefits of a token system, making nexus shards actually worth something to guilds instead of a guaranteed drop.
