I only play necromancer pve healer, pvp healer, and tank and seem to come across the same problem.
The Spirit Mender ability tends to not be within conal view of the caster. Many times I've found myself having to pivot around to locate it and thus having trouble using it's corpse for my necro heals and stamina regen. It takes many of the same animation positioning moves as the betty/bull netch for Wardens.
Also, the corpse doesn't last as long on the ground as the other temporary summons.
@ZOS_GinaBruno @ZOS_BrianWheeler could someone perhaps take a look at it to see if improvements can be made or if it is working as intended?
Anyone else (outside of dps) having similar issues with the mender skill?
