sssssstop giving WotA mana regen

the main champs that build it from what i've seen are Kat, Morde, and Vlad. what's the thing they have in common? MANALESS. Even when it had mana, you didn't see Mana champs building it a whole lot... it was the same manaless champs wasting gold for the spellvamp they needed

even if you make the finished items cost less, adding mana/mana reg. to an item means that if you're manaless, you might get stuck buying an absolutely useless mana item in the process of making your core stuff, which SUCKS (it's like buying tanky items early on for a carry or assassin... it feels terrible and delays your power.  BLEGH)

but anyway, i still heavily support percent pen only affecting bonus armor/mr, so that's good...
