Also I did email to the photon team about doing mmo, and they told me their server is built for casual games that are like 5-10 minutes long that needs a lobby. Not something that needs to be active 24/7.
But playfab will help you save your datas. When you start your game, it will get json data from playfab, you then extract it with a array. You also need to get the server time so then you'll know how long you logged off/on to give you the right amount of resources if you have that in your game. You also need to have a function that send data back to playfab everytime you equip a gear, use a potion, daily time cycle. If you update system with a timer, then you'll also need to get the server time and compare it with the current time to see if is done when they're offline.
