This reserve was not what was suggested and it is quite expensive for a facility to delete pets.
I explore my pets, but I still pay fees to feed them. Maybe I don't explore enough and breed/catch too much, but I don't have problems paying fees to feed them. Just saying, even if someone explores their pets, doesn't necessarily mean they can feed all their pets because of pets that are being tamed and aged. To have to pay that much for a facility just to delete the pets unwanted is a bit too pricey.
I'd definitely use it and see why it's that expensive when you base it on reality, but if you think about it. Like really think about it. You won't be able to delete unwanted pets until they're tamed. That's not the drawback, really. The drawback is if there's a price each time you send a pet to the reserve. I mean wow. Let's just keep on purging our resources. If there is no recurring fee, then I guess I'm a okay with it. I just want somewhere we can delete/release pets that aren't necessary. Like I keep on saying on these types of threads, it'll not only be beneficial to me, it'll also help relieve the server from having too much data. Lodging them for 3 days is ok for me, I just wished they didn't waste my resources. But if they won't sell due to their stats, I'd rather delete them off the game. That way they won't be data hanging around. I don't think that's healthy for the site over-all, having data just lying around.
The pound is not a public reserve. It's there so other people can adopt pets that are unwanted or are not part of the standards of the previous owner and either can't sell them or has a "good" heart (in terms of giving someone else free pets, but if the pet has 4 red stats on the wrong places, I don't see the good in that). Sending a pet to be housed there forever is not the goal and the point of the pound; suggesting to use it in a way that's not its purpose defeats the purpose of having one, in my opinion.
You don't want your precious level 50 with no breeding slots left to end up there and being adopted by someone else. You worked hard for that level 50, only to send it away for someone to use it as an explore buddy. What would you do if you need to free up space when you've maxed out your stables and can't let go of other pets because of the game limitations (taming, aging, important pets, ect.)? You'd have a liability on your hands and imagine if your other pets start to get to level 50 and have no more breeding slots left.
You'd be forced to delete them.
I have no problems deleting my level 50 pets, but a lot of people are sentimental and they have the right to be. Getting to level 50 without buffs and energy boosts take a lot of patience and time. It's not an easy thing. People will want to remember their pets and even if they can simply screencap it, it's still different having a hall of fame on the site.
I am glad we have a feature to delete pets because we have a lot of places where we can have data lying around (forever pound and no use level 50's). But if the reserve is there for deleting of pets, I agree with RedRarebit, Ankokou and others. If it's a place to simply remove pets, then it's expensive just for that purpose.
