Why is everyone still debating over this? Titans generate the most orbs, it's a [b]FACT[/b]. Even with Obsidian Mind/Bad Juju warlock doesn't compare to the amount that is possible by titans. Warlocks are limited to 9 orbs max. That is if you can find a pack of enemies and don't miss. Titans can create orbs from 4 different things. 1. Spawning a bubble 2. Bubble taking damage 3. Melee kills while Force Barrier is active 4. Kills with heavy weapons Sure a titan can only spawn a bubble or use Force Barrier every once and a while, but a titan with Ruin Wings makes it possible to run an entire strike solely using a HMG, generating orbs with every kill.
