My -hope- is that they're going to combine abilities or even make some into traits, and streamline the duration/cooldown timers on many abilities for simpler management.

For instance, DRG weaponskill "Heavy Thrust" could be nixed in favor of a trait that adds the effect of heavy thrust to "True Thrust" while increasing the duration. DRG weaponskill "Phlebotomize" could be taken out and have it's DoT added to "Chaos Thrust".

"Power Surge" could be made into a trait that increases "Jump" damage such that it amounts to the same thing in the long term.

BRD's "Bloodletter" ability could be made into a perpetual ability (like MNK "Fist of" abilities, ends on reuse) that adds an additional 150 potency auto-attack every 15 seconds, as well as whenever "River of Blood" procs. Timer displayed on hotbar and status icon.

Stuff like that would improve rotations and make it easier to maintain a proper DPS.

That's the type of change I would like to see, but across all classes.
