There is a lot of really toxic competitiveness and adolescent acting out that run rampant in competitive FPS...and some people just don't want to deal with it. Other people just have a personality that is more geared towards cooperative activities and than competitive ones. So they simply don't enjoy the individual competion that the cornerstone of such game activities. Still other people are older gamers who have lost speed and quickness over the years, and simply get tired of being "out-twitched" by angry 15 year-olds who mistake "youth" for "talent". I'm a middle-aged man, so I don't take the toxic nonsense personally....but even I find it tedious and tiresome at times. It's like going back to the high school playground. But with NO adult supervision to rein in the would-be bullies.

Mostly because I don't enjoy the community associated with pvp. I am the first to admit I'm not very good at it. Not terrible, but certainly not great. I am certainly not good enough that I would inconvenience 5 strangers by burdening them with my presence. But more than that it's that I really don't enjoy how people act in pvp. That's not say that everyone who is in the crucible is a raging douche, but not everyone has to be. There just needs to be one in the group to make it a negative experience. If I could play pvp with just my friends, as in my friends are on my team and my friends are on the opposing team I probably would play it a lot more.

Random loot system. Other shooters that do PvP much better. Impossibility of weapon balance.

Pvp does not help me level up

Notice how no one who is good at PvP hates it? Funny coincidence....

I'm not good at pvp and I do the daily pvp event and that's it. Sometimes I win, most of the time I loose, and all of the time I'm pissed off since I can't figure out when the other players are. When I do find them I'm dead. I should play more and learn the maps but then I would be pissed off all night. This is my first time ever playing a FPS so I'm way behind in the skill category but I'm trying lol

I'd say a few things: 1/ It's highly connection dependent. I live in a small country in which Destiny isn't very popular, so I'm playing with people in other countries, often quite far away. Lag is never fun. 2/ The structure of PvP encourages some sorts of play more than others - the maps, the movement speed and jumps, high-damage melees, and so on all encourage medium and close range play. I personally find stuff like 'Blink - shotgun' dull and would prefer not to be faced with that as often. 3/ It's too abstract. In killing enemies, I can put myself in the fiction of the universe and get involved. In PvP, it's shooting uniforms and capturing meaningless posts. If I wanted abstraction, I'd play an actual sport or something like Tetris. I find playing PvP makes me less interested in both PvP and PvE. 4/ I generally prefer playing cooperatively, and tend to get too competitive when I do get invested in a match. Combined with point 1, this isn't a good thing. On the rare occasions I am trying in a match and get involved, then get killed off by lag or get randomly disconnected, I tend to lose it. I'd prefer to avoid things that tend to make me do that. 5/ I find the push towards PvP in Destiny is frustrating. Four vendors take Crucible marks/rep, compared to one for Vanguard, and that's not including Iron Banner. Iron Banner is the only mode for getting level 30 gear without relying on RNG. Two of three events have been entirely PvP, with one being half and half. 6/ Nearly all the Crucible modes amount to some variation of Team or Solo Deathmatch. Even Control is only partially objective-based, applying multipliers to what's otherwise a standard Deathmatch set up. There's not much in the way of supporting your teammates the way there is in some MMOs, with buffs, debuffs, healing and so on for teammates who don't just want to do yet more shooting. 7/ Matchmaking does an awful job of matching up teams with parity or grouping people together into matches with comparable skill levels. It also throws pre-made fireteams against randoms, which is poor form - although some patch was supposed to cut this down a bit. Finally, there's no way to set up custom matches of any kind. For a big budget game with a heavy PvP emphasis, matchmaking is a huge mess. 8/ Balance isn't very good. Some classes are more powerful, some weapon types and examples are clearly better, level makes too much of a difference (with things like perk, even if health numbers are normalised), and secondaries outclass primaries by a lot, meaning you get a ton of 'shotgun v. fusion rifle' battles. I'm sure there's more, but off the top of my head, those are my justifications for not liking PvP.

Too competitive. I play games to relax after work and pvp is all tea bagging and competition and stress. I never feel like I’m accomplishing anything in PvP (not that the PvE in this game gives you a great sense of accomplishment either I know) Different people just look for different things out of games and find different styles enjoyable.
