I am echoing this. I too was really iffy about it at first, too. But eventually I realized that it was super hard to go back to playing Tales the "normal" way with TP.
You will soon learn how to get back CC more efficiently in the middle of a battle, such as by dodging attacks.
I agree. A Artes are way superior to basic attacks, because in the latter half of a Tales game normal attacks are damn useless except to generate TP (which is also not a problem due to using CC). At least with A Artes it's more flashier and has extra properties.
