I would say Warlocks and Titans are pretty even, and Hunters are the worse. Someone kills a warlock, the Warlock can self res. Someone tries to kill titan, the Titan can use Defender. Nova bomb takes a little bit more time to use, but is a lot like Striker. Striker is an auto kill, and gives you extra health. Storm caller is OP up close and mid range. Sunbreaker is OP close and far range. I like both warlocks and titans, and I use them both a lot. But the one I use the most is my Titan. Hunters are just horrible.
