So Lightning combat will use the traditional system (mostly? Like others pointed out something is up with the classes). I am intrigued already since I 95% expected a QTE-fest.
I think they did a really good job with the mage outfits, Noel's in particular. If they would have had robes the melee attack animations would probably look very weird/lame. Also really enjoy how they absolutely nailed the black mage pants, they are so perfect it's pretty amazing.
I know this is going off topic but if there is gonna be an FF13-3, the combat needs some revamping. I personally find that the system would work better if it resembled Last Remenant's combat system, or that you have a set of units battling against another set, one group has a set paradigm and another it's own set of paradigms which you can change to help win the battle. You switch control or observing a unit to advance through the game or battle.
This sounds like an entirely different game to be honest, not a bad one, but different from what the FF13 games go for. I think the only
realistic combat change I'd like to see is normal encounters having less enemies (1-2) and those enemies having much more HP than enemies in 13-2. I enjoyed the 5 to 10 second normal battles in 13-2 but I wish they'd been that short while making use of the stagger mechanic instead of just trashing enemies with AOE spam. It would actually be very similar to the original 13 that way.
