Before the CF nerf, I parsed around 20k on a dummy, getting really close to 21k...not great, but not bad. After the nerf I am hitting the high 18k area, just sneaking into 19k. This is a pretty significant drop when translated to ops. Before I was keeping up with other classes, I am now getting left behind by a considerable amount. Especially by lightning sorcs and tk sages. We have a sage/sorc hitting 12k to 16k in capped ops depending on the boss.
On average, in ops, I have dropped between 1k to 2k in DPS depending on the boss.
