I really love your idea for the F skills. So sad we're unlikely to get any kind of rework like that. :c I still enjoy the class but so much potential wasted. I was really intrigued when the mirage mirrors were first mentioned and the same for the idea of a chronomancer, but then in reality the 2 elites weren't very class altering at all, well not to the same degree as some of the other profession elite mechanics.
As for OP, I'd love shatters to be altered in some way, but I'm not sure how. I definitely don't like how clunky the 'running to the enemy and shattering' is with clones. It didn't bother me much when playing chrono because they could do it so quickly, but without that trait it's so slow.
