It is TOO much. I can understand that pets that are involved in the combat should be seen in combat, but otherwise, I would LOVE to have an option to have them turned off. My own and those of other players.
The same goes for non-combat pets. While I see that people like to run around with all kinds of things, I do not want or need to see them at all. The flying ones are the worst. They flap around, filling my screen and I really, really do not need or want to see them all the time. That goes for other people's non-combat pets of course. I can turn mine off whenever I want to.
