Im really upset the loss of this skill.Drain has been a spell in the blackmages repertoire since final fantasy one.I cant count the time this skill saved me in a clutch in a party situations when the healer is busy to heal myself really quick some to keep dpsing and in solo situations.If your damage was really high you could triple cast and top off to almost full hp.I remember the fight with the Blackmage chick in the steepe in stormblood,the one that has many phases,that was only possible with blackmage because of drain.So how will blm sustain his hp in clutch emergencies from now on? this is a big nerf that no one has mentioned but when you start doing stuff with blm youll feel it.Just because some people didn't use it at all dosent take away its value.
