The Esuna bonus is for mp conservation. Leeches doesn't need a change I would just like to have got it right at 30. 50 SCH and healed all dungeons from Bayfrox on with it without any troubles but I am currently leveling my WHM up and yeah things are simply easier. I do love the SCH play style but I never imagined the absolute ease of WHM.

Sorry for the sidetrack. ^^
