Constant "INTERRUPTED" spells during instances

I've noticed recently that I constantly get INTERRUPTED spell casts as a BLM. Specifically, it happens 99% of the time upon recasting a spell immediately.

It happens when I take no damage, no attacks hit me, etc. because I'm still at full health. Its just the spell simply stops casting... no movement from my joystick, as I'm on PS3, just constant interruptions.

This happened a lot before specifically during the Garuda EX instance, since that one was terrible on the technical level from the get go... but like I said, I'm noticing it in a lot more instances lately on PS3. I assume it has something to do with the terrible latency initiated with 2.2, but on the plus side the game isn't unplayable anymore... just bearable like it always was, lol.

Anyway, are any other BLMs noticing this? Is it a latency issue? PS3? Did 2.21 or 2.2 screw with BLM spell casts?

I noticed this myself but just assumed it was something to do with Spell interruption and I just wasn't seeing what was happening. I also noticed it during PS4 phase 2 beta testing.
