Honestly I don't get what the big deal is.. A proto- of something is short for Prototype, no? Or Primitive/First version of something..

It's no surprise that it's basically an easy version of Ultima.. (Even though it's lvl 60 and Ultima is a lvl 50 fight)..

The fact that it's just a tack on mini boss in a duty that most people are doing weekly is fine by me, it's just a free 270 accessory every week. If you want the trial version of Ultima then just do the old one unsynced or go do the FATE when it pops.
