You see, it's easy to say "you don't want to pvp? don't do it". I never did PvP in other MMOs I played but then you enter forums - toxicity beyond belief, grief towards certain equipment (even if you don't pvp and someone sees you with certain equip that is unfair in pvp you might get salt for no reason), in-game chats gets filled up with toxicity and general behavior of players changes all over the board. It's just sad truth when it comes to online games and players.
And it's why I love warframe - there is no this kind of toxicity, yeah there is complains and some toxicity here and there
