This is what i think was trying to be done with the early access for LE buyers. (though recent events would ruin it) (also i had a better explanation of this earlier but wasnt able to post it in a closed thread -_- )
To me because the people that got LE (myself included) “would of” got access to all the Specs early would make us the few like, hmm leaders? (or whatever the word is) on the battlefields among the many standard players. While most players would only be able to select from the 2 default Specs and the gametypes would be flooded with them; We would have access to any of them so logically most of us would pick the ones they dont have. This would give us a whole different advantage on the battlefield that standards would have to learn to play against and adapt to. (or something along those lines)
See i think after standards complete their first Spec THEN all the others would unlock for them. They will of had experience fighting the people with early access and know more along the lines of which Spec they would want to use next.
Thats what i think but as i said its all theory and kind of useless to be talking about now since they are making all Specs accessible to everyone.
