To summarize it, you are very displeased with the casting animation that costs unnecessary delay to your non-GCD skills and even unable to heal a player when he is raised.

From a Dragoon perspective,

I agree it gets very disappointing as this majorly applies to Dragoon players who jumps(all jump skills are non-GCD) in the sky and lands in an AOE unable to dodge it on time due to the long casting animation. Leg Sweep stun animation also has an illogical delay for me.

From Raise perspective,

To die again after being raised because of the unnecessary delay for raising as well, yes gets very frustrating, and a 30% penalty implemented after 2nd raise. I guess SE is telling us to also time ourselves with the raise, like don't raise yourself before Titan's Tumult LOLZ.
