Can someone explain to me what this means. No hate pls. kk, thanks.

I agree on that. I only saw Iron Man 1 and Incredible Hulk before Avengers, the others I watched after Avengers.

Assuming that everyone watched it on DVD or cable xD

WW is releasing before JL Part 1

Your assuming that everyone watched all the solo movies before the team up xD Look at the phase 1 solo film numbers then look at Avengers 1.
