I am as anti PvP as they come however (assuming the DZ is the same as the 1st game) you can solo or coop PvE the darkzone as well. It is worth it because (again at least in the 1st game) the loot is significantly better than what you get on the street.
When players instance with me they 90% of the time PvP me (and obviously they are always max leveled for the area with all the gear) so if this happens I just log off and do something else.
I got divisio. 2 gold edition for £6.50 over xmas, but want to wrap up the 1st game 1st. Fantastic title imo. My only complaint is that for me I don't like buying half games hence always buying gold edition of games or season passes with all DLC ... However ubisoft along with others have gotten greedy (imo) and now do multiple seasons.
That aside £2.50 is a steal even if it is only half a game. I have had so much fun with division 1
