The two character's don't really bother me it's just each character has to have 3 paragraphs at least.
Although if you were making a rival or just a new guy, I would wait till we finish the first mission, as people that wanted to stay will stay and those who want to leave will have fallen out.
I saw that you had near identical posts normally that would bother me, but I think it gives a chance at some hilarity. Plus your characters will stand out from one another when you write and react to the world. Unless you are the same person
