It's inevitable that account wide achievements is going to happen because so many players wanted it. However, there are also so many others that do not want the account wide achievements to happen(including me) for various reasons.
I for one would like to track progression I made where I earned specific achievements on certain dates when there is a date I more or less got carried to it earlier.

Honestly I don't care for the most part if there is a system like that, but only if I could decide not to have to join it myself.

So my request for this is: Can this global achievements made toggleable so I can decide for myself whether I want to do this or not? This way you suit to the needs of both those that do want the global achievements and those that do not want it.
