Dyna is the only FH card released on Duel Links with attack over 2000... it's their only beatstick. How else are they supposed to put in damage? Sure you can use Donpa's effect to destroy monsters on the opponents side of the field but that's now limited to 2 aswell.
Amazons wont be effected by Baby Tiger being semi-limited which I'm kind of annoyed about though.
Most of the time I won game without even use Dyna, Wiz is core card for Fur Hire, and I'm KoG. The fact you only depending on Dyna for beater you must be a silver tier.
If you only used Wiz to win as Fur Hires, then you either had Donpa to clear the field or you raised your ATK with Beatdown... which will now only affect Wiz so any 1900 ATK beater will stop your battle phase since you can't even econ take them either unless you give up one Donpa.
Learn some tech choices then if that's an issue... Be innovative and make something interesting that keeps it competitive or makes it even more competitive. The only time that it's potentially dead is if they outright ban a card.
