All those heroes you mentioned are well known by casual comic book fans, those are first tier heroes........There is a large chunk of casual comic readers or casual Marvel fans who had no ideal of who GOTG were till the movie was announced....
No they weren't. You are wildly rewriting history right now.
The Avengers were never a tier 1 team. They were tier 2, at best.
You're seriously telling me Thor is tier 1?
Superman, Spiderman, Batman, etc. is tier 1. Hulk, I'll give you. Thor? fukk no. Captain America? fukk no. Ironman? fukk no. Unless you roll exclusively with comic nerds I don't know how the hell you could think that.
What people like you fail to realize is
everyone is a casual comic fan now. How you think "The Dark Knight" did $1 billion? How you think "Avengers" did $1.5 billion? Off comic book fans?
No, off regular people who, generally speaking, don't give a fukk about comics. Like I said, you cats are stuck in 1992 where you think Marvel or whoever has to tap into some underground nerd market to succeed. This trailer was well received at Comic-Con, it was well received across the 'net when it dropped, it trended on Twitter....meanwhile you think "casual comic fans" need to OK this. Get with the times breh.
