Yup I just made a warlock. They are by far the most op and maybe even the most fun. As for you being new to the game in general. Welcome to the grind! Once you hit 31/32 at the very least make a second warlock so you can do raids twice and nightfalls twice. Once you have gotten a respectable amount of gear/weapons delete your second warlock and make all 3 classes. It's more fun to have all 3 then to just run the same class over and over again.
