Lets talk about the BLM job skills

[Isirus]

Alright, so i have been leveling up my BLM and i never really looked at the skills i would get for becoming a BLM. I just hit level 35 and got my second skill and was able to check out what my third skill would be, which left me feeling very disappointed.

After seeing my first three skills, i thought to myself "i don't think i will be using these skills ever." So i went and checked out my other skills they all felt very underwhelming.
so lets talk about them a little bit.

lvl30: Convert - Sacrifices 20% of maximum HP to restore 30% of MP.
Cannot be executed when current HP is lower than 20%.

This skill seems to only be worthwhile to get about 1 extra fire spell off before switching back to Ice, to be honest this skill would be amazing if it didn't have a 180 second CD, but with that long CD i find myself thinking its not even worth remembering to use.
