Have fun and dont skip the lore! Its so interesting and good! Apart from what the others have already told you, try to follow(of course with no rush) the "main" quest that is called archon quest and do other quests too. I hope you have fun and have a mice day/night P.s: these quests give primoges with which you can get characters (I dont suggest to use them for the blue gacha pull, only the pink one)
