Sticking this in Living World because this mostly pertains to IBS (though hints of it are all over Season 4).
Achievements and Collections are a good idea on the surface, giving goals to players and guiding them to content in the game or in a specific map and coaxing them to participate. No problem with that part in theory.
My issue is with many of the achievements being very easy to dot little collectables on the map and done to excess to pad the game.
40 little coins? Half the time lazily executed with no clues. 20, with sufficient hints, would be enough.
Do a meta 15+ times? That shows up once very two hours? For a mastery point? Offer the mastery point after the first run of the meta so the player knows it exists and did the content. 30+ hours of waiting for one digital cookie is unconscionable.
Catching events that spawn randomly? ..after a once-per-halfhour meta? Seriously? Don't gate gameplay benefits behind stuff like this.
These don't even feel meaningful. And no, I don't mean they have to be hard or "challenging" to complete, but any sense of achievement in them is lost in the gush of disgusted relief that we're finally done with them when we do finish. There's no contentment, only the sour taste of all our wasted time. Because we know it's all a game-time extending ploy and not fun.
Many alts! Handle it!
