I am in the process of reviewing all of the shard skills allowed for possessing the various obelisks. At this point I have identified several that are going to be changed. If you have suggestions for skills that would be interesting in those trees, please suggest them here. Efficiency will most likely see the most changes.
In addition, I am going to remove the SHARD ATTUNE skills. They remove the need to possess obelisks, which removes the need to fight over them, which defeats the whole purpose of the obelisks.
I would like to get away from skills that make existing skills better, and come up with some interesting new mechanics (easier said then done). I have ideas for a few of these, but I do not want to muddy the water with my thoughts.
Once again, keep it on topic.
