The introduction of more space on the vault has opened up the game again for me has I wasn't going to spend gems on that. I can now Hatch all those monsters I had collected including ledgenaries. The rune free at the moment gives me options to experiment with all the new monster I have. The only down size is I am running out of gems which is what sp wants so it's a win win as I am now spending again. Please keep the runes free going as it opens up the game.
