While it's possible to dual wield 2-handed weapons of you have Titan's Grip, keep in mind that dual wielding in an of itself is not a standard ability. You need to have something that enables you to do that for anything other than unarmed attacks. That's something that I'm seeing people forgetting, so a reminder is valid.

That brings us to...

Does Rocket Lancer have some Dual Wielding ability? If not, part of your last post is invalid. You may need to rewrite it.

PS:

Scarifar, your character actually cannot use two weapons at the same time unless you add this ability to his CS. Keep that in mind.
