Mend kinda sucks though:/ EDIT: Forgot it got buffed, guess it sucks less now, but still probably not worth 2 slots.
Well the 2 extra AP isn't actually great - the AP limit is still the same, so it doesn't really extend your threat range (especially as a lot of your champs will have Max AP after hibernate). Guess it could be good for 1v1 fights, but think that's about it. I'd drop them both and add a catharsis bloom and eriluuns favour (I would probably add other runes in actuality but these fill the spots of mend but do it better).
