Well, its all about knowing when its safe to do so. I ran a few coils early on as drg where the tank would have issue holding hate or didn't know how to hold still. One mis-placed jump meant that I'd be eating a hood swipe while I'm stuck in one place.
Other times, like for titan, its important to weave them in if you can during stomps or after abilities. Otherwise if you try too late during a landslide or weights, you'll be in big trouble. If the moves didn't lock you down and you were still able to move (think ring of thorns) I'd /probably/ use them more often. But because I can't always count on bosses to not kill me (Garuda EX, it doesn't hurt too much but getting stuck in an AoE circle that appears by chance under you) I'll sadly be a little cautious.

But when I can, and if they're both up, I'll use the jump boost skill + regular jump on an enemy between a combo or after a combo to work a little more dps in.
