I put around 200 hours into Destiny 1. The vast majority of that was PVE, strikes, raids, patrols etc with friends.
I did PVP briefly to get my crucible rank up sufficient to buy vendor gear or for those exotic quests that demanded it, and I would dabble briefly in Iron Banner when it was on, Trials of Osiris we did a couple of times and hated it; I've just never been a huge fan of PVP in Destiny, smaller scale stuff isn't really what I enjoy.
Having played the Beta, the lowered player count in PVP turns me off further, its just not that fun for me, so I don't expect to do much PVP in D2 other than on those odd occasions where it might be of benefit (quests etc).
