I don't have a problem playing Destiny with a controller, it's one of the only console FPSes I can deal with though. The other is Halo - Bungie has some kind of magic.
Either way, the PVP was very frustrating sometimes because it felt like I was playing against kids who grew up with Halo/COD on consoles, so I was a bit of a fish out of water. The worst problem was the FOV - someone could be standing next to you with a shotgun and you couldn't see them. I'd still dominate random casual matches against goobers but when playing with DestinyGAF or in Trials it was a struggle to keep up. The more seriously I took Destiny the less fun I had with it.
The PS4 community is great and I don't want to leave it behind, but most of my usual group of friends are primarily PC gamers. Several of those have hardcore MMO raider backgrounds, and I'd love to completely dismantle Destiny raids with them. But if for some reason they aren't interested, well, I still don't want to pay to play online anymore, especially after they jacked up the PS+ price in Canada. PS4 version is a tough sell for me.
Best case scenario is cross-platform play, but I don't think that has any chance whatsoever of happening.
