As someone who did Shiva Extreme when it was first release, Shiva Unreal is no different. The dps check is a little tighter than i remember, but if you have a group of people who either don't know the fight or keep messing up to the same mechanics it's not the devs fault.

As they said, unreal fights are the old Extreme encounters brought to the current level cap. If you're having problems getting a clear or a decent farm group then start befriending the good players you encounter in pugs so you can hopefully form your own parties with competent players
