What do you think on Stealth Battlers

There has been new beyblades with the title Stealth Battlers basically these ones have some sort of special attack I was just wondering what people think because it ruins all the fun. Having a special attack would pretty much wouldn't be fair. Also think of having them for the tournament it would be a drag having special attacks. So anyways I wanna hear from you guys what do you truly think on this new stuff going on.
We have been discussing it in the general Beyblade Metal Fusion topic already.
