Could this mean Monster Familiar may come to GMS?

You collect monster card-looking cards called "Familiars" which can be excruciatingly rare for all but LOW level monsters. When you get one, it goes to your USE inventory where you can double click it and name your monster. The Monster Familiar is then stored in your Monster Book under the "Familiar" tab. When you go to the Familiar tab, you will immediately see a list of monsters you have collected. When you double click one of the monsters, you can summon them, much like a pet, but they have the ability to attack other monsters and they give special abilities, such as increasing STR/DEX/INT/LUK, increasing Speed/Jump, healing you and your party members, making you transparent, making your character glow a certain color, etc. When summoned, the monster you have out will have a red sphere above its head with "気" within it, indicating its vitality. As it attacks a monster or boss, its vitality goes down. When it goes down to 0, it goes back into your Familiar inventory in your Monster Book and you cannot summon it until a time has passed that allowed that monster to regain its vitality. You can, however, summon another Familiar during the time the other one's vitality is recovering.
Also, if GMS were to get this, it's possible that they could also release the two special professions JMS released. With the Tamer profession, you can summon up to 3 Monster Familiars at a time.

This all sounds so awesome. I didn't know they attacked too!
I thought they were all just for looks.
