Ok, testing is indeed needed but it looks really too much nerfed, considering also that in he has never spammed in competitive playing.
Looking at it now I wonder whether it see still worth to play: as a summoner is not playble (you need a corpse, an high card of crow, an action to summon and at least another action to heal 2 damage...or you need another 8), as support master he negates - in a medium range - only one condition (slow) and heal 2 damage. Concerning offensive, he is less effective than a good scheme runner (2-2-3).
Said that, it looks like if you want to play him now you must choose nurse, chiaki and the poison build...still being a lot slow...
