Nah, not at all, I'm still very much on PC, but this was the culmination of a few things:
1: Being fed up of not having something I could really sink my teeth in to on PS4. I don't mean like CoD, I mean like Destiny. Hours and hours, with friends, long sessions, drunk, sober, day, night, whatever. A proper meaty game.
2: Not playing on PS4 enough as that's where the majority of the people I tolerate play.
3: Being fed up with WoW, but not enough to cancel my sub, but still wanting to put it to rest so I have no excuse but to get on the likes of Star Citizenships, Sea of People with Long Fingers, Mingecraft, Runt: Mowdown, etc.
I'll still very much be on PC, in fact this will likely increase my time on PC, just playing other things than WoW.
