@Koochi-Q I have no life and read it all.
I don't know about being ignored. I think it's an experiment to prove exactly how anti social and uncooperative "gamers" are with others. Make a squad based br and watch the gamers squirm when they actually have to interact with their peers.
My second theory is simply that Apex was never imagined to be as successful as it has been. Think about it, Respawn made Titanfall, to mixed degrees of success. Titanfall2 did much better in terms of reviews and quality, but being release sandwiched between bf1 and cod didn't allow it enough of a chance for market share.
So they release Apex, quietly. Probably anticipating that it would market to the titanfall fan base. Upon release it got more popular than they expected, and now they're scrambling to keep up.
