It's happened in every MMO (that I've played) that has had unique effects on the gear, and I hate it.

You can make them so weak that it just isn't worth it to be elitist over the special effects, but then I have to argue about what the point of it is if they're that negligible.
Or they can make it extremely grindy so that people won't expect you to have it.
