rune slots are an extremely important part of the game and it's really annoying when u craft a warmaster or hatch a powerful monster and get 1 rune slot so u have to spend gems after all ur effort to get it(like my burotgor). I say that u make all rune slots open. That way people will still need gems to remove runes so u wont have the thing of reusing the same runes over and over again and some will also probably spend gems to get good runes for all their powerful monsters. Upvote if u agree
