Mana Leech and Smith of Kitava Fire Spell

Hello i currently have 2880 hours in this game i truly feel like a have a good understanding after playing and testing alot of yours builds and skills. There needs to be spell leech nodes on tree or is bloodmage seriously gonna be the only spell leecher i would love to do chaos spell chayula with leech but there are no sources of spell leech. GGG if i dont see nodes or atleast a unique that makes spell leech apply to mana i will probably be a bit upset as that will open doors to way more builds. Also fire spell on melee smith needs a buff there is 0 possible chance you plan to leave that as is.
