I am in the same boat, bought the Xbox 360 for the Halo games and ended up selling it again for a $50 profit a couple of years later, Shooters on PC are much easier and precise rather than 'General Aim-assist' areas, Although there are definitely games that play better with controller (like Rocket League) so I always keep a controller nearby. That's awesome to hear Destiny 2 will be released on PC, I've wanted to play Destiny since the first game, however never actually got around to it since it was console exclusive so I'll be looking forward to playing that come September!
