Guild Wars 2

First off players should be able to name their “pets” and should stay active until deactivated by the player. Have them interact with their owner and maybe even by standards. A toy could be provided in the gem store that allows you to play fetch and other things (unique to each pet). Here’s where they could become useful, give each one a minor buff like a weaker version of the ranger spirits or whatever boon you can come up with. They don’t have to be powerful just helpful and/or interesting. Be creative and make them relate to the different pets in some way. This system could even be implemented with an entirely new class of pet.

Minis should not deposit when you say ‘Deposit all collectables’ as must players do this every 3 minutes to get rid of salvage materials taking up space. This is again a basic programming issue that has been ignored for a long time because staff is top-heavy and art/gem-store heavy rather than programmer-heavy.
