Lots of patches took place and the end result is.
Sorcerers are no longer a dps class. They can of course, max out their DPS and attempt to just attack only, but their dps doesn't compare to even tanks dps and so it is a waste of time until they fix the damage for them. FS is good, but even that somehow managed to get slightly nerfed. LOR doesn't critical anymore but it is fixed, healing wave/rejuvenation lost % in how much they heal. Overall, sorcerers just got wrecked and aren't enjoyable... but i haven't mentioned wizards.
I'm a sorcerer and I'm fine with my dps. My build currently is full dps with some skill points on LoR.
I agree that we got nerfed pretty bad, our hits and crits are not as high anymore, PvE wise, but it's still playable. I think aqua doesn't work anymore, with its hits missing 100% (I have no idea if they fixed this), but my dps is still good. Threat still goes up.
FS sorcs are good for farming/grinding parties that aren't able to look for a priest, but with the 1z skill resets out of the kafras, it would be a waste staying as a FS, since you can't change back to dps or hybrid.
