In WoW if you hook yourself up with level 78 blues, or end game 80 epics you get an achievement known as Superior (or Epic)

I have found a way to exploit the Rings and Trinket section of this.

Just switch the spots, and it will count as the opposite slot side also.

Unfortunately i do not have a high enough level trinket, or i would show you this also. But it does work as proven by a guildy.
I hope you enjoy this, it saves you time from getting 2 more pieces of gear which can sometimes be difficult.
