I do like PVP for several reasons. The main reason is gimmick and unique LB, the close second is gear independent, and the last reason, limited chat.
I used to play alot of PVP games, but most games aren't exactly flexible or unique in their designs.
Some games, every single class is the same with some differences, but it boils down to being very spammy.
Still, those games are designed based on 1-1 situation so the design is going to be different from team-based design.
Unique LBs are pretty much like Ults from MOBAs, a genre which i also play. Love it.
Being gear-independent is very very fantastic. Most game i played, PVP progression mostly tied to your gear, and level, and you need to grind the shit out of it for eternity. cough coughKorean and Chinese MMOscough cough Now i dont have to grind those gear, put up with the notorious enhancement system, or powerleveling every single patch and can log off to do something else. Still, there are games that are good at gearing system, like Guild Wars II for example.
People might say limited chat is bad, but for me? Im too tired from handling a lot of foul-mouthed kids and adults from other games. It doesn't matter if i win or lose, i just absolutely despise these people. I know trashtalking is very common in competitive environment, but being respectful is also a common sense and courtesy.
There are some toxicity, yes, but i had a lot of experiences in open-world PK cesspools so its not that big of a deal. However, i do understand why the devs are very sensitive to toxicity and i don't disagree with them.
