I assume you are referring to Icebrood Saga. I'm actually just playing through it on my second account. Currently close to the end of Drizzlewood 2.

IBS is really weird. You mostly hear very bad things about it, but when you actually start playing it, you probably think "WTF, this is amazing. What are people talking about?".

I think IBS starts very strong. e. g. it has the best event in the game, loads of detail and very immersive maps and story. Sadly the Norn part is not as detailed as the Charr part and the overall level of detail diminishes the further you progress in the story.

I think what we see is a game that was destined to go into maintenance mode. Hence the rather grindy masteries and achievements. And then we can see a change of mind/direction, i. e. another expansion (EoD) is coming. Hence we see this rushed ending with 2 Elder Dragons being killed off within a few minutes.
