In my experience, teammates will very often run the ball into the enemy half of the pitch, then immediately get tackled. Obviously they should pass to a teammate before that happens, but they clearly don't feel the need to. I find the lack of passing makes the game borderline unplayable, and I'm not sure what the fix is, but maybe this will help.
I think asking them to pass (pressing R3) doesn't work because it's like you're asking them to do a favour for you, so instead a "look out!" reframes it like you're doing a favour for them, and might help encourage passing.
I would also suggest this new quick chat option replaces the "thanks!" option, as I rarely see it used, and I feel like "we got this!" is a close enough response if someone wants to thank their teammates for a "good job!".
will be interested to hear people's thoughts!
