I have one of three characters, granted I haven't put much time into playing warlock but I feel like I have a firm grasp on the classes. NOTE: don't confuse most skill for the best class. Warlocks probably most useful, but that's a different conversation entirely. Also, most skill does not mean that the other classes do not require skill. OK, so this is what I think. Warlocks: Warlocks have a good skill tree with and all that. Great subclasses with extremely useful super. But the thing with warlocks, is that there are perks that support common play style. Titan: I play the most amount of time on my Titan. I'm not prejudiced in favor of Titans but this is what I think. The entire foundation of titans is melee on both subclasses. Getting up close and personal with every goddamn enemy. You want health regen? Melee. You want a shield? Get a melee kill. Shoulder charge is all about melee. Although the perks compliment each other well, playing as Titan is difficult because it takes gamers out of the traditional play style. You have to play differently in order to receive the full benefits of each subclass. Hunter: I feel like the perks that the hunter have don't really compliment each other. They're all kind of random tbh. Therefore I believe that it's not difficult to play as hunters because the simple act of killing enemies will trigger perks. Note: I'm not saying hunters are bad classes, I really enjoy playing as hunters.
