That's still not forced crucible and gambit are still very optional you don't have to participate if you dont enjoy them. There are many milestones now just for pve. Also quests are optional for example if you're referring to the recent Thorn quest, its a well known pvp gun so requiring pvp at some point to get it is valid. The only thing I can think of other than that is the allegiance quest steps for crucible kills and banking motes in gambit. Bit annoying yes if you don't enjoy those but still optional. You could always be a neutral guardian :)
