I think with auto attack they will need to change the buff system. Currently the buff system works most of the time for "the next attack" - which at the moment you can choose and control what and when this attack will be. However, with the addition of auto-attack, this gets a but flaky (mistimed SATA anyone? lol).

Maybe they will opt in favor of the duration buffs like in FFXI.

AND if they're redesigning buffs. Please, PLEASE let "raging strike" be called Strong draw or something. Raging strike just doesn't make sense for an archer.
