The answer on who is "BigA" is so simple, but SO SIMPLE, and it was hinted since season one: Mona was able to get rid of Alison. She became "A" to torture the Liars. Alison stole the game from Mona... Remember, Ali said: " I really should do something about "A"... That bitch is genuinely getting on my nerves.", because she didn't want Mona to be in the spotlight, so she made Mona work for her: "I did everything you asked me to."

Just like Peter said: "Complicated problems have simple simple solutions.". It makes a lot of sense!
