Honestly? I'd look at tweaking the timers for abilities next. Along with reducing melee/tank to 30% and NIN to half of that.
A shorter cooldown on Purify and/or Guard would make a substantial difference. I also think that Sprint needs to be changed from unlimited to a 30-50% uptime short cooldown - maybe like 8 sec duration with 20 sec cooldown. Unlimited sprint is a problem for melee characters, as unless you can chain CC's together, you can quite literally just run away from melee/caster attackers and there's surprisingly little you can do about it.
Unlimited sprint is fine in CC due to tiny maps, but it's kind of an issue in the larger environments of FL and RW.
