I see your point it would rattle up job system for sure. But is that really a bad idea for FFXI?

making ppl have to test out new approaches to the current setups could be very interesting and might even lure in some old players maybe even new ones.

Just imagine if one of the War slot abilities gave any job "Provoke" that alone could open some interesting doors or to keep to the Passive Trait route be something like Enmity generation multiplied by a large number.

Something drastic like redesigning all the jobs from top to bottom could bring a new age to FFXI but thats another topic.

For fun i'd like to see creative ideas of possible slot abilities for job classes. I'll add to original post a template for the fun of it.
