I noticed that the Hybrid Core Melee powers break Hide on a stalker. If you do nothing else but simply activate the power while hidden in the middle of a mob, the entire mob will suddenly attack you. I know the Hybrid Radial Melee powers have a taunt component and will break Hide on a stalker - but was not expecting the Core side of the Incarnate tree to have the same effect. The Core side of the tree is not supposed to have any taunt effect. I mentioned to a GM and they said that was not working as intended and to report in this forum as a bug. So - duly reported! 🙂
Thank you for your help and all that you do!!
