Not sure if Turbine has even touched base on this, and if there has been a post similar to this I apologize, but if the issue hasn't been properly addressed then it should be.
Should you have too much DPS it is very detrimental to any party in the Shroud and the VoD raids. Whatever fix Turbine made to the combat mechanics in Mod 8 should be looked over and redone properly for Mod 9 or reverted back to Mod 7 standards.
Mod 7 standards are the issue at hand I believe...somehow maybe there was too much of a problem with people standing in place and swinging whilst running-but you ended up making the problem a bit more 'problematic' in specific quests. Don't make the quests harder due to poor testing and broken code.
So if the issue has already been addressed then I apologize, someone link me. Otherwise I look forward to a fix and discussion of the problem here in this thread. Thanx...
