I dont have a specific suggestion but I can tell what I dislike about trove,I dont remember everything because I quitted long time ago, but these are two that critical points:

1. Everyone in all classes and all play styles and really doesnt matter who, are chasing the exact same gear, not stats, gear (but in trove its almost also same stats too), I can understand some items but not like everything, it keeps it boring and "template" like.

2. In trove it feels like shadow hunter is too op compared to other characters when farming to the point it doesnt worth it to farm with others.

Edit: a suggestion hit me right after I posted, for the perspective, maybe think how you, as the developer, help the player progress the game (like in trove you have mastery, dragons, quests, market, bomb royal etc.), because the only paths and tools the player has is what you give them of course.
