Too be honest Serpent Stance right now in blizzard current alpha iteration is very easy to refuse.
On Crane's Zeal vs Serpent stance I am not so sure. Blizzard has said that we should be healing around 50% of a healers heals, whether that factors in Crane's Zeal I am not sure. Even if it doesn't we would then have 70% of a healers heals, but that might be worth it to not have to channel and etc. I would like to see blizzard respond to how much mana crane stance/fistweaving will cost in mana, it still looks like 8% so far. Though ths all could change once we get some real gameplay numbers in here.
Really? No losses here.
It seems like they changed it +295.747% spell power(115.747% up from the current one). How much spell power does it take to turn a bad spell into a good one?
