Wowhead mining show a change to the illusion spell in the misc spell changes, so it looks like it *is* staying but is no longer a Nightborne racial. I assume its prob going to be a toy afterall.
The Force shield is hardly OP, its pretty much useless on a ranged class and any melee already has better snares. The dmg is also low and was reduced in this build from 5k to 4k also, think its staying right where it is.
