Group Finder Tool

I’m quite certain it does.

Nope, if five warriors are first in the queue, guess what group comp you’re rolling into WC with lol

I recognize this, but do think they can make decisions with decent discretion.

Something like this can be accomplished with an addon, and that is probably the best option for OP. I doubt Blizzard would add it for the reason you mentioned, but as someone who started day 1 in vanilla I don’t feel an interface change to facilitate finding groups would be detrimental.
