Now I don't know if this is legit however I have heard they are changing the squad from 5 players to 4. If this is the case this is a horrible decision at least for myself. I play with 4 other mates every night and it will be a big shame to have one of us miss out because of this change.
The other fear is that it's clear they want squads to work together ie revives, health, ammo etc etc. Half of the time when you have randoms in your squad they are flops...they either camp or roll scout at the worst possible times. If they drop it down to 4 if you have one flop everything just got that much harder.
That's my 2cents.
PS; Trailer was terrible.
