Can't beat em? Join em! The pro really is worth it for BF1 though.
Nah. I'll still have the same doubts, only it'll be whenever I win a close fight instead of when I lose one.
"Did that happen because one of us is using a Pro and the other one isn't?"
I'd be somewhat happier if there was a 'Pro' badge on the scoreboard beside every player using one, like when playing Mario Kart Wii you could see which players were using motion controls. At least then you knew what was up, and it gave motion control players bragging rights over analogue users when they came out ahead.
I might end up getting a Pro down the line for the improved single-player games, but there's nothing on the horizon (pun intended) that I see myself making the jump for yet.
