What changes would you like to see in 4th job skills?

What I would like to see is IF they can change ice demon so monsters would become weak to fire elemental attacks, but ALSO keep their own elemental weakness instead of making them neutral and making other main attack crappy f3.

Or make it weak to their other element. Like Ice Demon makes the monster weak to Lightning, Fire Demon makes the monster weak to Poison (Paralyze).

Summons should've also been their "secondary" element. Some Zeus/Thor summon for Lightning and for Poison... a Medusa-like summon? Well, something way better.
