" From this moment the stats of the wild pets won't be visible. It's very hard to ask a wild pet to run through an agility or cross country course in order to see what agility and constitution it has. First the pet needs to be tamed and properly trained." - Angel (this suggestion, page 1)
"We can return back the visibility of wild pet stats if you will agree that you can't do anything with the pet before taming is finished even if you don't like this pet. [...]" - Voron_eril (this suggestion, page 2)
As far as I'm concerned, they have a "logical reasoning" behind hiding the stats and if we agree that we don't do anything to the pet, they'll bring it back.
I do think it was a poorly decided move as this is a petsite, not real life. But they also said integrity is important to them (also on that thread), so we have to choose if we want this over seeing the stats.
For me, I'd rather have the option to release pets before taming as it provides many benefits. For one, I only catch 3 types of pets (Unicorns, Pumas and Cockatrices) and I'd rather NOT get white unicorns. Having this option helps me segregate my pets and choose the ones I want to catch. Regardless of seeing the stats or not, I will at least have control over what I catch and not take everything from the wild.
Second, it purges data that could potentially clutter the site. If I catch a Gryphon for example, I currently would be forced to take it in. Come the time its stats are revealed and it has red marks, I will have to sell it. If the pet doesn't sell, I would be forced to send it to the pound in the hopes of someone taking it in. For example the pet has red stats in Strength, Agility, Intelligence, Courage, Blow and Rush, what can the new owner do with that pet? Sure, gather and explore, but battling with that on an island is going to be one tough task and you can't even up the stats properly. Unless someone else wants to breed the suckiest stat Gryphon ever, then this has no use to anyone.
If having the option prevented me from taking this pet in, letting it go and deleting it from the site, it will not only help remove unwanted (and never wanted) pets from the site, it will also clear out clutter from the site. The pet won't stay in the pound forever since it was released at the beginning. Though since the stats are hidden, it will still help remove unwanted pets by its specie. If the pet has good stats, well, it's not what I want to catch and I don't know the stats so it's a risk I'm willing to take. It uses up my resources and I'd rather not risk wasting it on a pet I won't even get anything from.
I understand that they need to emulate an environment at the moment. The very least is that they can confirm that they will add this feature or something similar after Beta. If they don't want to, then it's their call. If they want pets to be sent to the pound because of too many red stats (say hi to this Cockatrice of mine, what can you even do with that?), then so be it. I just really hope this doesn't clutter the site and slow us down.
Also, penalizing people for releasing a wild creature is like telling people they should just catch everything from the wild. If we base it on reality, that's like over-hunting and it won't be good for the environment. I am going here this since this is how the game developers see their site. I know the pets are unlimited right now and there won't be a risk of environmental disasters (it's a game, unless it's programmed to happen, it won't), but if integrity is important, releasing unwanted animals to be able to live its life in the wild is a good thing.
In technical terms, we're helping remove data from the site. It clears it up, removes clutter and helps prevent the site from slowing down. It's a positive thing. They've also mentioned that there are other ways to find pets to breed with so we don't have to catch pets for "fresh blood." With that, being able to release a pet before taming doesn't jeopardize breeding. I don't think people should be penalized for that.
