I'm really happy so many people still support this amazing content.
Everyone but Square Enix it seems.

I still have a small sliver of hope that they'll continue the content even after November. I mean, it's not like adding a few monsters each update can be considered a major update, right?

The three biggest things I want to see added to Monstrosity are (in no particular order)

1) Party mode. Somehow, someway monipulators need to be able to team up, gain exp together and eventually tackle ridiculous bosses. All SE has to do to make this entertaining is add some more areas (for bellingery as well) and kill the exp penalty for teaming up. This ALONE would bring back so many players to Monstrosity...

2) Rewards. Sure, leveling the monsters is fun but after a while you need an extra reason. As of now the rewards are ... mediocre to put it mildly. As suggested, add some rewards to (PvP) Monstrosity which we can augment through infamy and / or prestige.

3) Monsters who have reached the designated levels to obtain instincts should acquire these without setting them. It's ridiculous that a Behemoth needs to set its OWN instincts! Have them become available automatically at level 30, 60 and 90! This way you can create even stronger monsters.
