Dissipation doesn’t give mana. A sch main should know this. But it’s not like sgn gets in these 3 minutes two times rhizo for 2 stack that are worth 14 % mana and heals. So in 3 mins worth of fight sch gets 15 stacks AF were 9 are from atherflow and 6 from dissipation funny enough you still only get 60 % mana back. Sgn in 3 mins has 11 stacks and every single one gives 7 % mana so in short 77%. Like again you fail to simple read a post that just says sgn gets more mana then sch back.
Also you lose the fairy for a whole minute for 6 AF stacks. So fairy has 3 recast so you lose 1800 potency while doing that and that times 2 there is a reason sch has the lowest mana sustain of all the healer.
