Just to clarify the passive does not take into account any external bonuses, ONLY health from base stats and items. So itemisation for any champion to suffice for two or more requirements would be extremely unlikely.

However, out of all the things concerning Ryvar, his passive's requirements were the most fiddly. I wanted to make it so that it would be easily recognisable for Ryvar as to whether his target was say an AD carry, an AP carry or tank, and be able to aid his ally in that specific field especially (along with other helpful bonuses). If you still think the requirements should be higher (taking into account the point made at the beginning), I would be very happy to change it.
