I don't understand what is going on here. I pug most of the time (if it matters my inquisition level is a touch over 250), and I haven't experienced the AW "problem".
If a player is running at a pace you don't like then either vote kick him or find another lobby. Start your own lobby?
I'm not really sure that players are all that concerned with the post game medals. On my archer, I've recently taken to hanging back a bit just to keep the reavers, assassins, alchemists happy with targets to kill. If I'm not #1 in the end, IDRGAS; anything I needed to prove re: kill shots was done in the first few promotions. Maybe I could see getting a little competitive with someone in the group if they are playing the same class as me, but aside from that I just don't get it.
When I play my AW, it feels like easy mode. It is almost like the devs intentionally created a character to prop up bad players, so instead of getting upset when someone is ripping it up on an AW, mentally I just give them a condescending pat on the head and say "Yup, you really ARE the best, Timmy!". It almost seems cruel to remind the kids in special ed that they are handicapped. I couldn't imagine feeling envious of them.
And yes, sure, a skilled player can perform wonders with an AW. While I certainly don't count myself among them, I imagine they are bored while doing so.
