Buffs on self that aren't important
These are procs that you can't really control (eg. some happen every time you crit), and that have no real effect on your gameplay choices while they're active (eg. increase attack speed, but you're going to attack all the time anyway), so you'd only want to show them if you're really curious.

Buffs from totems that aren't important
Usually you won't care about seeing these buffs, since you'll just look at the duration timer on the totem itself. The only reasons you'd want to see these as buffs would be (a) you are obsessive about micro-managing other people's positioning and wish to yell at them when they move out of totem range, or (b) your raid leader is an obsessive micro-manager who will yell at you if someone moves out of your totem range and you don't move your totems immediately. Otherwise, the totem duration and some basic situational awareness should be more than sufficient to use your totems properly.
