Given the amount of champions in the game today more bans had been something we've needed for a long time. And noobs or not, Darius is frustrating to play against and sometimes people don't want to deal with that. It's like the Blitzcrank Paradigm: If You Don't Ban Blitzcrank, He Will Be There.
Even though Blitz and Darius aren't OP per se, they're not fun to be against and that's what bans are for. If he gets nerfed, he gets nerfed. But if not, his ban rate might go up a bit. Every champion goes through a weird ban phase and Darius is no different. He won't get banned every time and with Pick Intent your team won't ban him like 99% of the time. I think you and all the other Darius mains are safe for now.
