yeah, I felt that when I read about the scarlet halls achieve. Before it was pointed out I thought, hey it doesn't say heroic it cant be an exploit but i got it fast in case it was a mistake. Then i noticed some of the achieves said normal or heroic. I guess blizz thought normal dungeons deserve boss mechanic achievements.

This is an exploit. Or atleast a kind of.

The level 85 version of "Theramore's Fall" scenario is a FoS achivement, and shouldn't be counting towards the 100 scenario wins achivement (I asked a GM).
When MoP is released, there will be a level 90 version of the same scenario (Theramore's Fall), that will be counting for the achivement.

That's my guess of what's OP is trying to tell us.

so you believed something was a potential exploit and you went and told a GM about it?

Scaled down to 85 for one week or not, the feature is still a Scenario and is working as intended. This is in no way an exploit, no need to desperatly try to label it as so.
