I am absolutely certain of this - fun is why we play games. If we want to learn, we go to school or do research; if we want to work we go do that.
Playtime = Funtime. Period. Remember, Blizz? Fun.
The Darkmoon Faire is fun. Transmogging is fun. Transmogging heirlooms is way fun. You get my $15 per - in return, I want fun. Please do not restrict the delightful parts in the game. Do not leave us with stress, steep learning curves and work.
We want to transmog our heirlooms.
