Thank you very much for the information.
That's what I would like to test. Since Rouse is suppose to lock the pet stats in at the "owners current value". I doubt the effect would stack each time it is used, because as you say, that would be "broken".
What I do want to see is if: Summoner Skill Speed 500 - Enhanced Pet Proc + 20% - Summoner Skill Speed Stat is now actually changed to 600.
Activate Rouse - Pet Skill Speed is now locked in at 600.
So if the pet skill speed proc'd again afterwards - the Summoner Skill Speed would only go to 600 again, which if you popped Rouse again, it would only lock in at 600.
It would be interesting for Scholar if it did work that way as with new gear you can reach 530 Spell Speed with food. If you use Fey Glow with the Spell Speed proc and Rouse you could lock your pet in at almost 800 Spell Speed.
