I was such a happy boy when I finally settled on these auras... aside from being pretty pleased with them in general, it's nice to have a much readier means of seeing just what's being done to you by aura-enchanted enemies.  First one I came across  was 'aura-enchanted', then the Conviction bubble popped up over it's head and mine, and I knew exactly what was going on for once ;).  I never liked a single one of the paladin's auras except for Salvation, so I didn't pay much attention to them.  The descriptions are to clarify what's happening, or to point out the anim I used.
