I do wonder how many relevant CEs for the soul shards people are actually completing. I would suspect, not that many relative to the other CEs. I would then ask the question, are you actively trying to spawn the relevant CEs?

Oracle was my last soul shard I needed and it just would not drop, not that that CE spawned often. So, what did I do? I actively went after fans between CEs rather than going after FATEs to try and spawn the CE more often. Everything considered, it really hasn't taken that many of the relevant CEs to get the soul shard drops, at least in my experience.

It is all well and good saying you have spent so much time in OC that you have almost maxed out all your other jobs, but how many times have you actually had the chance for that soul shard to drop. That is what matters.
