Waiting too long to bring the X-Men. It has been 4 years since they gained access to them, and at least 6 years since the merger process started moving ahead.

I'd say this is a big one for a lot of people but I don't think it even necessarily is just down to the X-Men. How many years has this fanbase been going on about wanting a character like, Nova for example.

So when you hear Marvel is doing an Echo show or a Wonderman show. I think a lot of the reason people are so down on the idea is that they're characters like Nova that Marvel is just dragging their feet on introducing. It's been 10 years since we first met the Nova Corps. 5 years since Infinity War and he was part of an early start of that movie from the Russo's themselves.

And just nothing. They have plans to do something but they just seem to have no interest in getting it off the ground anytime soon. But they'll do a Wonderman show in a heartbeat.
