Hmm...yeah I'm not too happy about unupped Firestalls now having SoG available to them. There was a suggestion to make the unupped version heal 2HP instead of 3 while keeping upped as the same, but I don't know, 2HP would make it practically useless.
Not fond of the +1HP bonus with a Life mark either. The extra healing is useless to Life as both Druidic/Jade Staff and Heal are better substitutes in the majority of cases. Also, if I wanted to focus on a
deck centered around nothing but healing I'd rather use Adrenastaves or a Bond deck; the healing is just completely overshadowed. And as for using them in a stallish deck with a
mark...there weren't very many of those that existed before the change so I'm inclined to doubt decks will bother making the switch to make them more competitive now. It's a bit of a nuance, but not much else.
But I guess the main purpose was to nerf SoG, and it's been nerfed.
