This issue was posted months ago but never seems to have been addressed. Xaku's Grasp of Lohk cannot attack any enemy that is in a ragdoll state, this includes things like Khora's Strangledome, Hydroid's Tentacle Swarm, Vauban's Bastille, Mag's Pull, Gyre's Coil Horizon, and many more. Is this on DE's radar or being addressed at some point?
In this current state, I would argue that Xaku is somewhat unplayable in public sessions, since his biggest kit doesn't work majority of CC frames.
