Summoning/unsummoning your pet in the middle of combat will remove your overlays, allowing you to potentially hide some things from people in combat, such as your invocation aura now being gone. Coupled with Mask of Metal or Trickery, which negate your ability to see status debuffs and buffs means this could get situationally dumb. 



(Also pets still aren't the source of pet-say and pet-emote, making it so they're sometimes unhearable if the pet owner is behind something or far away)
