Increase buff durations across the board
The tedious process of maintaining buffs is an unfulfilling chore. Buff durations in general need to be more in line with that of Protect and Shell, in that you apply them and then don't have to worry about them until they are either dispelled or wear off much later. Having to constantly renew buffs makes for poor gameplay and I think the overall game experience would be much improved if buff durations were increased across the board.
Buffing should not be a tedious chore, it should be something done as preparation for an encounter.
