2. I'm pretty sure, even if they finally decide to make Enochian as a toggle, they will add some negative effect. Like 0% chance Firestarter proc inside Enochian (unless after Sharpcast) or Scathe has cast bar with some % dmg increase.
Bliz IV giving UI : No, this isn't how they want it to work.
3. 15 secs is reasonable. 30 is way too much, u can even fit all your Fire IV cast inside Enochian with just 1 AF refresher.
4. BLM can finally stand beside melee in single target DPS contest. Do they need to stand beside SMN in multi target DPS contest too?
Freeze, Sleep and Lethargy are the spells I used the most in PvP. Apocatasthasis saves my tank's ass everytime when magical tank buster comes. Surecast isn't an exclusive skill to BLM only, they need to think 5 times to make a change since there are 5 jobs using it.
