Pretty mediocre experience. I enjoyed the game a lot initially, but quickly lost interest in reading what NPCs had to say or in completing sidequests.

After the campaign, unlocking higher World Tiers, completing Whispers and defeating World Bosses or fighting in Helltides was fun for a while, but past level 70, the only activity that makes you progress is clearing Nightmare Dungeons. And man, reaching lv. 100 with my rogue was such a boring slog.

After doing so and defeating Uber Lilith, I leveled a HC Sorc to lv. 50 before calling it quits.

Not really a game to invest more time into. Pretty casual experience.
