I did a quick exercise, as follows:
Several of your level 5s are duplicates of pets you already have at 25. I eliminated them.
I eliminated those where the breed of your level 5 is different from the breed I have. This may seem egomaniacal, but I did put some thought into my breeds, so as a shortcut to cull those I would not think worth levelling it seems expedient.
I then went through the list by eye, and marked
- priority 1 for those I would not want to be without, for battling purposes,
- priority 2 for those I have at least seen being used in PvE or PvP
and I deleted several from the list by eye because they are duplicates, for battling purposes, of pets you already have at higher levels, like Rabbits and Frogs. I don't say that they should be thrown away; just that I wouldn't prioritise them this week, which is what I assume this is about. Some I left as priority 3, like Muckbreath, which is a moveset duplicate of Snarly, but Snarly has a better breed.
I did this from a battling perspective. You have some valuable pets in that list, like Eye of the Legion and Nightsaber Cub, that you may want to level for that reason, but I left as Priority 3.
So, if I had your collection, the Priority 1s in the list below would be the set I'd be absolutely sure to level this week.
I'd like to get the chance to do the Priority 2s.
The Priority 3s could wait if I got tired. (And I'm sure I've just insulted someone's favourite battling pet
