You're never going to balance it perfectly, ESPECIALLY not by throwing more types at it. Sure, you might shift WHICH types are at the top, but not that they're at the top themselves. Something is going to fall by the wayside.
And you've even said it yourself, dragons are OP thanks to their stats. Offensively, they're only SE against themselves. Plus, a good number of them have 4x weaknesses. Granted, most of these are for ice, which sucks (and apparently fairy is going to make that even worse). If GF really wanted to go for balance, it'd be much easier to just readjust move power or stats, than to introduce an entirely new type.
