I feel the opposite, personally. Rather than some minor buff you try to keep ticking all the time. they should make the skills only last 5 to 10 seconds, and actually have an appreciable impact on the game when cast. Protect actually forming a major mitigation barrier, and at the gold charge immunity to damage for the first couple seconds of the buff. Haste not being a buff that makes you say, "Well... I think I may be swinging a little faster... maybe..." and instead, "Holy WOW! I am so fast right now!" for a couple seconds when you really need it, like when the boss gives you an open window.
