So, by OP's logic. All Extreme/Savage fights shouldn't be locked behind their normal versions right? Why didn't OP complain about that and instead started crying when Ultimate was announced?

Ultimate has the same criteria as Extreme/Savage contents. You have to clear their normal version before you're allowed access to Extreme/Savage.
You have to clear Savage before unlocking Ultimate.

I don't see the logic in OP's complain.
