As a Warlock in 2v2 2k+ , QE was the standard before the new badges came out. At first I was skeptical, but after using the badges, I would say it is a must for 2v2, 3v3.

For 5v5 though, I could not find the use for it. I would say only select classes would need it (those who would be the burn down first).



Now if you are just takling about regular battlegrounds and not arena, then don't waste the honor/badges on the BA.
