Dynamic Queue needs Tertiary and Quaternary roles.
I understand that for 2 people, 3 roles need to be selected in total, that rule can still apply if they were allowed to select Tertiary and Quaternary roles.
I enjoy 3 roles, and am tired of deciding between only 2 of them, because if I wanted to Que for more than that I'm subject to the other 2 roles I dislike.
Some may think it's not that big a deal but for many it really is..
Some like to mix it up, some like to have it mixed up for them.
P.s. Dynamic Queue is a leap in the right direction, but can be even better(duh).
