Simply put its it's viewed by the dev team as another type of ballista/brenner system instead its potential to be another jobs added player based system which is why I bet there is no party based system included into monstrosity as of yet in a weird way. The idea back when they had added newer jobs through expansion packs and added on scenario add-on packs was that these jobs were going to be called advanced jobs to the jobs all ready into the game but I found this not be so true with the exception of blue mage's versatility to incorporate all types of jobs in the game into its job system in various ways taken away from each job. now blu in my opinion was the only true advanced jobs they came out with playing.

What i'm getting at is that I see monstrosities potentiality to be as another whole advanced jobs system to be played but it lacks the job play plot in battles system that everyone that comes together or gets on that particular job to play all to be successful in tasks incorporated into the game or tasks carried out to complete mission/quest storylines that expansion packs or add-ons with those jobs have on them as a role but we all can see the more ideas in this way that monstrosity could be done, specially if the system were being set up to play in a party based system among all of other jobs that we already play to get stuff done. Someways this kind of reminds me of pet jobs and trust characters as well.

Now What I've liked about monstrosity is simply that its not so heavily based on your requirement to search out for all of those gears needed to play that particular job which is through monsters as a job in whole over jobs all ready included into the game but as someone has come to state with the bard job has its limits with how many songs it can cast to be used at one time in which case I'll add my idea of making some equipment only usable by mons with the item in your inventory and leave it to you guys in how it can act equi[ed but remains in your inventory, I guess in a way it be like using ninja tools in your inventory to cast various spell's.
