Re-rushing is somewhat lame, I agree. But let’s face it.. about 90% of the dungeons I’ve been in wouldn’t have been accomplished without this mechanic. Massive numbers of enemy doing insane damage with mega health… I think you guys lost the concept of “challenging, but manageable,” and nerfing AOE and mechanics which allow average players (i.e. not VOIP or raid-nazis) to complete battles is a step in the wrong direction.
What you’ll see with this is a lot more failed dungeons with everyone quitting. I’ve already got to the point where after two attempts I can pretty much tell if a group has any chance of making a battle or not and will quit groups. With this… why even bother?
