Strange, I am the opposite. I find this to have more depth to the fighting and I grasped it quicker than I did Graces. Which character did you use?

I've grasped it a bit better now but it's still harder than Graces for me.  I used Graces on 2D planes though, and I do have Xillia on that as well but it never seems to work.

Alvin at the moment & my mate is using Millia.  

If you're jumping, you're pressing up on the stick. Try not to do that lol. I was actually having trouble getting the jump to work at the beginning, though that stopped being an issue after a while.

Also play Jude.

Anyway bugrimmar if you haven't played a fast-paced RPG like Tales before, you just have to get used to it. You'll get the hang of it eventually, including the subsystems and such. I mean I've played lots of Tales but I still needed time to adjust.

As for switching links, I don't know what the issue is for you as it actually is really responsive and quick. Just get used to it I guess. With switching characters I thought it was a bit awkward due to the button combination needed to switch. I'd try not switching characters too often if you're not getting the hang of everything else. Switching characters means you should also know how to use them, but if you're just trying to move them, it might be a bit much if things are going too fast for you. So I'd leave that for later. The game isn't that hard so you won't be needing to switch characters mid-battle much. If you just want to control another character for a while, put them at the top in the menu outside of battle.
