A fantastic expansion added on a fantastic game.

Everything added in Iceborne fixed most of my flaws in world
-a bigger, better and more varied Monster Roster
-a much, MUCH better hub in Seliana, with a gathering hub I actually wanna be in.
-a great new endgame in the Guidling Lands, which is probably the best endgame in the series.

Most weapons got new moves added to the moveset as well, pretty much improving on all of them.
Not only that, but the DLC it got later down the line is all fantastic too, with Fatalis being one of the best and hardest fights in the series.

Its not all perfect though. The clutch claw was a fun idea, but could have been implemented way better. They gave monsters too much health because of tenderising, and you basically want every part you hit to be tenderised.
However, I beat the story my first way trough without ever using the claw, so I wouldn't call it mandatory.

Another problem I have is the balancing around the dlc. The later monsters added in dlc pretty much force you to at least invest a little bit in what the meta skills in the game are and make sets with those, because these monsters have DPS/element checks, or just one shot you if you don't have health boost. And after beating Fatalis and making his set, you basically never have to make another set anymore after, its that much better than the rest of the armour sets.
Older MH games didn't have this this problem(or at least, not this big) and I wish I could see more armour variations.

1500+ hours and still playing. A must if you are a fan of the series, or if you already own world. Don't get world without this.
Worth even full price, but its on sale often.
