Here's the thing, the OMAC duo is not a challenge. Its just a simple puzzle. And yes the OMAC duo has always been this way(since july 2011 anyway, since thats when I started playing). Once you separate the two OMACS they die pretty easily. I've been doing that duo since T2 was the best armor you could get with marks and getting T1 gear was actually a challenge. It's not something that needs to be fixed, its not a glitch. It is just you whining because you are unwilling to adapt to such a simple challenge that requires a bit more then smash, smash, SMASH! This is a place to report bugs, not complain about something that YOU think is wrong.
