Agree with you. 1.0 animation captured my sense of realism in slow walking, fast running and coming to stop animation.
As for the lock animation while mage casting is pretty annoying sometimes especially ifrit hard mode, it can ruin a chance of winning the fight.
I'm sure ARR will reduce as much animation lock during magic casting at least up to the first 60-75% of casting before getting locked in. The fast casting spell are the ones we'll have to decide closely since its nearly instant or a 2-3 seconds cast. We'll just have to use our decision during an intense fight and hope nothing goes wrong, which i hope that wont be the case.
