Blacksmith Multicast mana management

[Token]

Very basic concept, if blacksmith doesnt multicast, the fireball only takes the original 125 mana, but for each x multicast it takes an extra 20 mana or so, which equals up tho the current cost of fireball of 185 regardless of multicast.

1x= 125 mana
2x= 145 mana
3x= 165 mana
4x= 185 mana

This would benefit unlucky players, who multicast only a few times within an entire game, but still pay the extra manacost; would make blacksmith that touch more viable

i don't think blacksmith needs this buff, he is already a strong hero.
it wont matter all to much anyway late game since he will have tons of regen and tons of mana.
