From my experience it can take a RDM from a 1:30 to 2 minutes to completely buff. That alone makes a 30 to 45 second to short to even crank out half of what we need. I'll admit some buff's my be redundant. But add on possible buffering of other's and that number can be pretty much on time. One of the reason for including a longer duration of the actually 2 hour is to flush out the over all utility. Not to mention it will just make the player base feel better about using it.
