Why is burst so.... unimpressive?

[Mychael]

I was very much so unimpressed but as with all other skills from Blm other than Freeze, which is really nice.
Only thing I can see it being worth the 15 minutes was if it gave you MP instead of costing.

Convert is really nice too! :]

I've used flare before to wipe rooms of lower mobs, but it seems like I could get off a fire->fira combo during the cast time. The only advantage is that I can position myself to hit more mobs.

Freeze is wonderful.

I've already begun using sleepga regularly.

I've used burst twice. Once to do meh damage to Ogre despite being at 158 HP, and once just because I enjoy watching furry animals die. Does this really deserve "15M" status? I think not..
