You ironically only have a Warlock. Play a Titan. Use the striker. You need to know how other people feel about using other classes. Restricting yourself to 1 character isn't a great idea. Try another class, get used to it, and you'll feel the pain other people have. And there's no point in "Getting used to it" when Warlocks are one of the most played classes and have arguably the best super in PvP.
