As for cards, details are listed in game but the majority of changes were buffs. Of note are damage increases for close range cards and AoE cards, cooldown reductions for healing cards, counters and AoE status effect cards and cooldown reductions for piercing barrage cards (excluding Stellea's). Section 4 got a measly nerf of a 4 second longer cooldown but 3% more stats - I was really coping that card would get gutted.

Noctis really got a chunk of pretty big buffs, can't say I think he needed them but I guess they want to ensure he sells.
