I had a hunter through the majority of the game and got him to max level and he was my main. And then I made my warlock and I haven't gone back since. After getting a warlock to 34 I realized that hunters really aren't that good. In PvE the only thing I can think of them being useful is going invisible and dismantling mines in Prison of Elders. Tbh they're only good in crucible, and even then I would still prefer my warlock. I'm always gonna have love for my hunter but in all honesty, warlock is just simpler, more practical, and just more fun.
