I've personally been loving monstrosity more and more with each update, so I wanted to start a thread of wish list items.
My top 5:
1. Parties! Being a monipulator is currently a very lonely road. I would at the very least love to be able to xp with other monipulators (in or outside of pvp zones). Being able to xp with adventurers would be great as well, which segues into...
2. Beastmasters and Monipulators, a match made in Heaven('s tower)! If not becoming full fledged party members with adventurers, I think it would be really cool to allow a monipulator into an adventurer's party as long as there is a beastmaster present for each monipulator. The beastmaster's role would largely remain the same– they can use their same job abilities, rewards and such to aid the monipulator, and likewise the monipulator's AOE buffs could extend to the beastmaster (or ideally entire party). I think if allowed to events like wildskeeper rieves, this would be a fun mechanic.
3. More Desirable Rewards for Adventurers! While I think the current pvp system is designed very well, I notice very few gladiators participating in it. Some extra incentives might help.
4. Uncapped PvP Zone(s). Another reason I think there is a lack of gladiators is because they can't take full advantage of their fancy item level equipment or level 99 job abilities.
5. More content Monipulators can participate in. I can totally see many reasons to exclude monipulators from content such as Dynamis, Salvage, Voidwatch, Abyssea etc, however it would be nice if monipulators could participate in some of the more casual content like rieves, campaign battle, and besieged.
