If it was like TT where you could choose your level of difficulty, I'd be for this. I mean, I run FCC quite a bit for mats and what not, I would like a challenge from time to time. However, they would either have to borrow bosses from other instances or create new ones. We all know that Agatio is capable of doing just that, as we've seen in the revamped TT, I just don't know how hard it is to code new bosses in. He could always make all the bosses level 200 and all the mobs 150 in hard mode. The biggest question would be how logical the drops would be and if it would unsettle the economy, were those dropped items introduced. It's not a bad idea, really, it just depends on how well it's executed, should Agatio decide to implement it.
