I've recently hit G rank and mostly play by myself because my internet is a b****. Anyway, I've soloed most of the content with the weapons and armor you're expected to have.
That being said, I usually clear mission in under 30 minutes the first time around and work up to killing monster in under 20.
Whenever I play online with a group of people the game just loses it's interest tbh. It goes from hunting a challenging monster to ganging up on the poor thing and stagger it until it dies. If people bother to bring along items to speed up the kill like traps or flashbombs then it's just sad.
It's honestly pathetic how there's no scaling done for the game.
Scaling was done for village/guild with guild quests taking into account multiple players (not how many players are in a quest).What you should be complaining about is why they're scaled so low. The answer to that is the game was originally a 3ds game and the developers wanted the Japanese (their target audience) to be able to finish a quest during the commute to/from work ordering their lunch break.
if there were scaling, why would you bother hunting with other people? the idea of teaming up to make a fight easier just kinda makes sense.
There's more to teamwork than just damage. Even by scaling the health, it would be advantageous for people to hunt in groups of 4 for traps, flash bombs, status effects, healing each other, stuns, etc.
By not scaling you can just wail on a monster and stagger-lock it until death.
