One thing...
Just because something's made of a hard metal does not make it incredibly sharp or deadly. Cap's shield is obscenely resistant to harm, but doesn't just slice through things, because it isn't designed to. Even Wolverine's claws, which would be comparable to Pred weapons, can't cut through steel (Colossus) without a significant amount of force. (more than Wolv by himself can produce) Hard metal does not guarantee infinite slicing power. It can be made into a sharper edge, but it can still be blocked by lesser metals. (sorry, but the total disregard to physics was REALLY getting on my nerves)
Oh yeah, and plasmacasters can blow a hole the size of a football through an unarmored torso... That's from Concrete Jungle. It's not quite titanium, Cyclops would be hard pressed to blast a hole through a thick layer of titanium with his visor on, but the casters are still fairly powerful.
