I think the roster is fine, the problem is how pointless so many of them are. All these tempered monsters about but they're all dropping defunct stuff - feels like I only had to kill most the non-Apex monsters 4 times each (1 for main quest, 1 for optional in each LR & HR) with some not even that.They didn't learn anything from world in this regard.
currently HR 40 doing the apex hunts, only got the forrest one left to do and I'm loving the game. Low Rank is a mess and I really don't like the story but it's a lot better in High Rank and closer to the typical MH fare, looking forwards to digging my teeth into the end game weapon grinding, some of the stuff people are doing already is crazy, para cb in particular looks insane.
I'm becoming a bit sus of the monster roster though, unless there's quite a bit left to unlock it's a light roster and no rapters to kill is sad even if the variety is better than world. I don't know why they didn't port more stuff from older games, 6 ish years of development after their most successful game to have one of the smallest rosters they've done in a while? It's dissapointing.
That "strength" star difficulty exists for field surveys but it doesn't actually seem to impact rewards and all the "normal" monsters just seem to reward the same pointless junk of low rank jewels/low rank Artian components.
Big missed opportunity, the game has no legs right now. A proper "live service" game that's released feature-limited to push out as patches with FOMO events.
