Dificult charecter build

[mysnametaken]

I'm trying to create a character that requires more skill to play then just fire your spell swing your sword and follow the tree.
like the old DDO where feats had to be taken not skill treed. a melee sorcerer or wizard required a fair bit of challenge to learn and play but was still quite fun. Unfortunately since the addition of skill trees the eldritch knight path made this mute as they just GIVE you the feats making masters touch, shield, and mage armor pointless to pick up.
any ideas?
