Really. It's not from me, it's from developers. At start game have classic quests like "kill X mobs", now we have quests what have a lot of triggers, riddles, a lot of quests where we need protect something or have timers. We have more lore based quests, when at start only epic quests was lore filled. At start all mobs just fight in place where we encounter them, now they use CC, ranged mobs take distance from you, some mobs with low health run away from you.
