So your answer to a debate you aren't even in, is to nerf them slightly because people suck at mechanics and can't get their clears? Sounds like you are in the "nerf RDM" camp.

Furthermore.... Those 6 minute clears are from groups of people that have tons of practice and generally have a rdm and a sam in there. Take 4 MCH into primal EX tell me the clear times.

The EX primals were an example, not an arguement. Want another one? We don't even know what savage will bring and people are screaming for nerfs, for all you know rdm and sam will be the reason for the clears. You don't know what kind of DPS checks will be needed.
Want another reason to stop screaming for nerfs? WE STILL DON'T KNOW WHAT BUFFS WILL HAPPEN TO THE JOBS!
