Exactly - I am playing the Beta on PS4 and Xbox One to see the differences for myself and I must say that inviting people in the Fireteam on the Xbox One is easier and quicker than having to use the PS4 messaging system... On Xbox One you only need to click on a player and invite him to your Fireteam and a pop-up like an achievement appear on the window saying the invitation was sent... On PS4 - you click the person and then invite and the PS4 messaging system appear... takes time to load... then you need to click again for an invitation... load... back in game... too much button pressing for only creating a party... Hope they will improve the system... as it is now... It makes me thinking of getting the game on the Xbox One just because it's more seamless in the process of creationg a Fireteam...
