Since about the beginning of this whole New 52 thing, DC has teased us with potential Justice League rosters that contained heroes like Lady Luck which swiftly got scrapped and forgotten. In addition to this, DC had been teasing us with a "Trinity War" since about forever, and in a tiny little teaser we were shown Mera, as a member of the League, getting punched by the greatest female superhero of all time whilst wielding a cool pointy circle. (image) That thing, however, turned out to be a bust and it was just Martian Manhunter pretending to be her for a few scans cuz reasons. Now, as well all know, Geoff Johns, writer of the Justice League, loves Mera (source) and he has been able to add some of his favorites to the League like Captain Cold, but for some reason he keeps not adding Mera with every roster shakeup.
Is there any good reason why we haven't seen Mera join the League, yet? I know there's always the explanation that she doesn't have a good motivation to do so, but honestly is more up to the writer. We know that if Johns really wanted to, he could easily give Mera a reason to join.
In conclusion, these are my questions:
-When do you think Mera will join the Justice League? (if ever)
-Do you actually want her to?
-Is Johns dropping hints that I'm totally picking up on?
