Why? D:
The SkS/SpS changes seemed pretty good, with the other changes in mind, I was dreading SkS overtaking CRIT, but those CRIT changes put those worries to rest.
I get the feeling they're trying to even out the three stats (hence the DET nerf, since that was by far the winner currently), rather than leaving DET/CRIT as the dominant choice for most. Only potential issue is MP/TP drain when stacking the stat, but I kind of see that as a good thing; it encourages balancing out the three, rather than stacking two, and it's something which would be dependent on the Job at hand. MNK, for example, will probably be getting a lot out of SkS now, since it's getting an additional TP recovery skill, meanwhile sux2bNIN, though those increased returns on CRIT have me salivating.
