You can string things together pretty well. like Warp Strike + aerial combo with the short sword + switching to big sword for a final big strike.
You can teleport while in the air doing an aerial combo by expending a little bit of mp. This can make for some awesome and satisfying combat where you're dancing around in the air while teleporting to dodge his strikes. (Works on ground to an extent too, but I found it cooler in the air

)
Warp strikes from high points deal massive damage, so if you get higher up on buildings and lock on, you can deal massive damage.
The other weapons add a lot more variety and should be there from the beginning.
Weapons do have special attacks too. I think the big sword can do a spin attack if you do the ground combo while rotating the left stick.
Pressing Square at the right time rather than just holding it doesn't expend MP while holding it would.
All in all, I found it very fun, and I think it has a bit more depth than a lot of people breezing through it once will prolly find. What it really needs is a good tutorial to show how to do the cool stuff with it.
