Flat white is 2 espresso shots and equal parts steamed milk. A Latte is more steamed milk (idk the exact ratio if there is one), most places just fill up whatever latte cup they have which should be bigger than the flat white cup, and has a small amount of head/foam.
Yeah, but the point is that you aren’t just grinding levels. You literally said it yourself, you go explore a different area, you play more of the game (not just grind the same part of the game)
