I gave most of my feedback in-game yesterday, and rather than clog up this topic with the same feedback as others, I thought I’d raise this thought.
As it stands, the group setup has to be 1 tank, 1 heal, 4 dps. I know that it is possible for most classes to sign up as different roles, but when running pug groups, most people just sign up as their main role. Understandably, this is in place to safeguard against unbalanced groups full of tanks/heals, but it does make certain things a fair bit harder.
This is particularly the case (imo) for the dungeon finder (pre-80 dungeons, purist etc). Running with only 1 tank in these dungeons will often make them significantly harder/slower (thinking about the average player, not uber t6 players making characters for purist runs 
A solution to this might be difficult, but I’d imagine possible in one of these ways:
For dungeons, require 2 tanks, or make the requirement flexible to have 1-2 tank, 1-2 heal, 2 dps.
Allow people to sign up for multiple roles - a POM/TOS could sign as HEAL+DPS for onslaught
Loosen the restrictions for onslaught roles, allowing 1-2 heals, 1 tank, 3-4 dps
Would be interested to know others opinions on this…
