Renown isn’t an issue. You have to do dungeons to level. Simply play the game and you get the renown passively. If you don’t like dungeons maybe this game isn’t for you. Blizzard seriously messed up when they said “play your own way”. People take it to literally and want this concept in every aspect of the game but it simply don’t work like that. There will always be meta’s and you have to do things you don’t like if you want to clear end game content.
