Unlike us "hardcore gamers" not everyone is going to be willing to wear 2 different kinds of armor set and look like a complete tool just to get a few extra points in whatever irrelevant stat it is. Min/maxing isn't that important and the main reason to have both Myth and Allagan gear mixed is to get enough Acc to beat Coil, which not everyone wants to do. Not everyone cares about running raids for loot, nor is everyone capable of clearing Coil.

Like someone else mentioned, some people feel intimidated to do Coil, too. I, for one, didn't do Coil until I had a few Myth pieces because I was worried about ruining runs for everyone and I don't have an FC I can run with.

I don't really get the point of this thread. "Oh, hey. Look at all these players who don't take this game as serious as all of us. We is so cool because we have 5 more Crit than everyone else!"? Allagan gear is kind-of unnecessary for anything outside Coil.
