How about an endgame event that has all of them come together at the same time?
It would be insanely fun to see an army of useless woodland creatures, dwarves, undead and other creatures attack a base at the same time, possibly attacking each other. Sounds like a super messy battle./s

The way it is handled right now is logical by design because its bound to your progression.
Earlier raid events are pointless to the player due to the progression. Having Silver and Blackmetal gear doesnt have me getting thrilled when some Boars and whatnot decide to attack me.
Uhhhh, what they gona do?
Boar me to death?

When you defeated a boss, that boss creatures are no threat to you anymore.
Dude, i have killed the bosses already easily, their mobs are trash, why would i bother?
When for examplei defeated Bonesmass, the only threat to me or my base comes from Lox and Fulin Berserks.
Thus i dont need earlier raids at all.

Your proposal isnt thought through.
They designed it correctly at this point and theres no reason to change it, because doing so would contradict the design.
Gamedesign works for a reason and you have to think about a lot of stuff when it comes to it, as all things are logically connected or some solutions are there because it would otherwise not work well.

Yes, Valheim has some areas it needs work to be done, like combat being god awful.
But the general design is rock solid and doesnt need changes from some amateurs on the forums.
No insult intended, but the general majority of the players have 0 idea about gamedesign and as we say in German "Schuster bleib bei deinen Leisten".
Which means in some way, talk about something you know something about.


The only solution to your proposal would be, if all enemies scaled with your progression so that the raiding Greylings or Boars are much much stronger than the regular counter parts.
Which doesnt work for several reasons. As said, gamedesign means stuff is connected. You cant just change X to achieve Y.
