Yeah, same. My friends and I play this game on ps4. However, I am more of a pc player and I do best playing PC games. But I can't play with them whilst playing on the PC at the same time sadly.
Once I heard about the cross-platform idea, I was immediately intrigued and am currently praying this will become a thing.
I don't really care about cross progression since my stats on ps4 are bad. But I understand that some players have quite a few wins, kills and have possibly bought some things. That too would make the game fun and increase the number of players playing it.
