You do remember they get access to ONE single spell after a long rest, not the whole list.The normal spell list is already strong. But have two full spell list at the cost of a single long rest??????? If you find this is balanced...
I am a powergamer, and this really only has a small amount of weight in terms of build consideration. You already memorize/learn most of the best spells on your list already, there simply aren't that many spells that will become encounter winners in niche situations that you'll also know about ahead of time. Maybe some divinations for planning in long downtime situations?You are probably not the only one. But think about it. You'll see things our way. A lot of the cleric and druid spells are niche by definition and intent. Not so with the arcane list. Having the whole spell list, and in some cases two (a subclass) or even all spell lists (lore bards) is incredibly powerful! At level up, it forces the player to think carefully about his/her choice. At a simple long rest (especially the non gritty variant), it is simply overpowered. If you ever saw a powergamer or min/maxer, you'd understand.
