Disable activations during CTR/Seige/Etc
During events in particularly CTR the ability to activate turns it into just a rotation of sitting with merien shield on.
If activations were deactivated it would make for a much more enjoyable experience when coordinated pushes are actually able to achieve something besides making the holder of the relic activate until the enemies push is stopped
I agree with the idea of whoever is sitting on the relic not being able to activate merien shield. All other activations should still be useable. It's rare as of now for a push to dislodge someone from the relic once its on its altar. It would make CTR more fun if there was more chance for back and forth.
