Diablo Immortal

Currently downloading the game to my phone. I have never played this particular Diablo, but I have played the first 3 very much. I'm going into this with open eyes and an optimistic mind.

Now I have no intention of purchasing anything. My goal is to see how far I can get into this game before it either stuck behind a pay wall or it becomes an insurmountable grind.

Those that have played it, how far into it did you get before you put it down?
