I've seen many complaints about how many monsters there are and such limited space. Especially around breeding events. As opposed to just adding more islands and upping habitats which ends up with just too much gold in the game. What about making another lvl to the monster lab. This new lvl would allow you to hibernate a monster. These hibernated monsters would be stored in a vault so you could view what you have. These could be thawed out when needed common 1 minute, uncommon 5minutes, rare 10 minutes, elite 1 hour, legendary 10 hours. This would give flexibility to freeze or hibernate monsters for events and wars without having to add new islands habitats or change balance of gold production. This would especially help with common uncommon and rare monsters since the restriction iS used in wars and dungeons but most people don't want to waste valuable island space on them.
