the thing is... lore wise they should be able to take over the sc universe no problem... but a force like that would make for a massively unbalanced system....

Actually, Lore Wise the Protoss are the most powerful. Not only is their technology massively superior, giving them force fields and blades made out of plasma, capable of cutting through any physical material, but they have psychic powers. In order to make up for this, they all have massive unit costs, but a Zealot should be able to insta-kill almost any zerg unit with a single hit.
