I guess it's how you approach the game. LOL. Aren't all MMO's/RPG's essentially the same thing? Make a character, do quests looking for loot, side missions, story missions, upgrade character, skill tree, play with others if you like. This game checks all those boxes.
I'm not sure what you would call the DZ. At times it leans very heavy in PvE and other times it can swing PvP but you have the option to just leave the area and not partake in the PvP. But it is a lot of fun when you have a collective mass of fellow agents tracking down some douche Rogue's and then it almost feels like PvE.
I, along with countless others, can't help but compare it to Destiny. IMO this game, so far, is a far better experience in terms of what is offered and how it's delivered. One thing I hated about Destiny was that I could walk into an area, kill the bad guys, get the loot, and then go back to where I entered the area and it would reset everything just as it was. I haven't seen that here. It could happen down the road but so far I haven't seen it.
Plus it has a ton of side missions and chances to "help" the world you are in just by wandering around and keeping your ears open. Reminds me of RDR in that sense.
I for one am enjoying the experience. I love the chaotic aspect to it, I love the Tom Clancy angle, so far the story is interesting, and co-op makes it even better. It covers a lot of what I'm looking for in an experience but that doesn't mean it's right for everyone. But for me it's in my wheel house.
