If you don't want to play the game but only to get the rewards that's what I'd call simplistic and lazy. The quest for the skyscale is a lot of things, but simplistic and lazy definitely not. So first set of collections are almost identical (the scavenger hunt content), scale scale and eggs could have been less items but more engaging than just find 30 items.Second set was visit old meaningful places, perfectly fine with that, in fact liked it, but it's another scavenger hunt and not all that different from the first setThird set is, as you called it, resource investment, which was disproportionate as some weren't as lucky to have the time-gated resource on hand (but anet changed it due to feedback)Fourth set jumping puzzles and minigames, I actually liked the ball one and hope we get a ball as an item so we can do the minigame anywhere at any times as it could be a good time-killer between events and time gates.Fifth set with the final two collections. The saddle which is another phrase for "we know you dislike it but please spend more time here", to be honest that's my problem for liking hot maps way more than pof ones.And the flight which again is another scavenger hunt, not very different from the first set I don't mind the mount being hard to get, but it isn't. Wouldn't mind the mount requiring even more map resources if so many collections weren't alike. Tedium of going to 100 places just to press f when at least half of them are meaningless, is lazy design (as someone already pointed it out, it's how mobile games work).
