Who can, or is willing to, advocate variable damage weapons like axes & hammers, hand bombs, etc.

I just don't like the idea of "hit or miss" damage. The only reason I can see for using them is for inflicting status.

So what other arguments are there pro or con?

The same thing goes for a lot of the technicks:

is anyone "consuming all MP to change the HP of an ally to 10 times that amount?"

or "consuming all HP to revive a fallen ally?"

or "casting a random black magic on a foe?"
