How about more detailed filters for people looking for a premade? You have color codes for lets say, soo normal as green, heroic as red, such as "SoO10 [11/14]" in green text. Why not take that a step further and have drop down menus (like you already have for voice) so users can select any of the raids like "SoO" or "FL", then drop downs to sort those "SoO" groups by normal/flex/heroic and yet another to sort by what boss the group is on, either by that bosses number or name?
