it helps in some very particular situations i guess (lokke Hm tombs?) but cant be any better without becoming mandatory for all healers.
unless ZoS makes healing staves' LA/HA to heal instead of deal dmg, but this is far from happening since it could change healing in its entire form.
just put this skill aside for now.
it could be for sure, but it isnt necessary at all right now, that's what i meant.
if it becomes something that MUST be done, then this will need a long oversight because of the potential "need" of friendly targeting system with friendly priority target and so one.
i havent tested mend wounds at all, but i guess heal the right target in a group of let's say 6 with eso packing combat style is awfull
