I believe that the tiger is a great asset to BSTs. I think that he does great damage and I can imagine that he is going to be my pet for soloing when I don't require a special pet to get the job done (like leech for Sedna for water resist). He is stronger than the rabbit, but I wish that one of the TP moves he has can be a little stronger.

On the slug, I think that he is a great situational pet. If you need a pet that is very resistant to water, he is going to be the one that does the job for you! Other than that, I think he does decent damage at best. I think that his two TP moves are essentially useless. Elemental attacks have proven to be useless. The "Charged Whisker" from the lynx seems to do only like 500 damage ONLY if you have the proper magic attack atmas, other than that it is useless. I think Square Enix should consider giving pets more physical attacks since they are stronger. I don't know how well the Bio and HP Max down works on NMs. I think that needs to be tested. SE should consider giving the slug something else besides the moves there.
