This is a joke, right? Please be a joke...otherwise...raging over ONE pets mechanics? Really? Mechanics every class can learn to deal with? The only class that has a very hard time with this pet is guard, and even guards can kill it - if they use everything and think of everything that can help them. In other words: If they play like everyone plays...? (Or they wait until they have better gear, like with every other content that is too hard at the moment for you.) I will not even begin to argue about particles not turned on - Kurt had me rofling at: don't implement something fun or challenging because reasons.
The point of a social arena is that you can watch and be watched - if you like this concept is up to you. That includes waiting for other players to finish their fights. Every player has 3 minutes in the arena, and he can use them the way he wants, may it be trying to fight a challenging pet, finishing one easy pet of in 20 seconds, or running in cirlces for 3 minutes. What do you care, you have to wait anyway, and that has absolutly nothing to do with one pets mechanics, but with the concept of the arena. The mistake is in the system, not in one unrelated part of it. There are discussions about what is wrong with the system, and it is most certainly not one particular pet.
