I noticed you're rocking the bad juju, gotta love it! Also I main my warlock(as you can probably tell) and once you get him really leveled up you can make him just as bulky as your Titan with defense and recovery. Granted he won't have a defender shield but he can still self res and that's pretty useful in strikes and very useful in the hard raid! Also void walker works awesome with bad juju, nova bombs forever! Happy warlocking :)
