Along with swinging the weapon in relation to what the player is doing with the rThumbstick. YES!
To the guy being a troll below me.
Think about the options that open up if it did have that feature.
You know that rThumbstick could easily mimmick all the new sword swinging action that is going to be in that new upcoming Skyward Sword. I think its called.
Few examples of how the rThumbstick could have made melee combat more engaging.
You ever remember playing stuff like Fight Night or Ready to Rumble. How they did the boxing punches with the thumbstick controls?
Now imagine this. If you hold both thumbsticks left your character strafes left and vice versa for all other directions possible.
Other than that. any other movements with the thumbsticks dictate what kind of attack you make with that hand. It can be done. But only if you used a lock on feature for melee combat.
I'd say that even magic could take advantage of unique thumbstick movement patterns to determine what kind of spell is cast from it.
Example.
Simple movement of back to front cast a stream version of the spell.
More elaborate motions of the thumbstick can create a cone version of the spell instead. or and radial effect.
This will only be possible with a "lock-on". so that the rThumbstick controls the Right hand instead of looking up down left right.
From what it's shaping up to be.
When the player depresses the Right trigger. Instead of swinging the sword, it engages lock on. and then transfers control to thumbstick so long as right trigger is held.
The Left Trigger would need to play a role in switching the Lthumbstick between movement/left hand actions. But in the process you need to make sure that while the L-Trigger is held. Players still have options to strafe out of the way.
