Hello everyone. I'm just getting back into ESO today after having experienced a bunch of bugs after launch that diverted my interest from the game. I'm happy to see that the bugs have been ironed out and that there's new DLC, including Elder Scrolls staples like The Dark Brotherhood and Thieves Guild, but I've searched everywhere online to answer some curiosities of mine and have come up empty.
Simply put, I like to play Elder Scrolls game to theme. My super honorable sorts probably don't join the thieves guild, my honor-among-thieves characters aren't necessarily dark brotherhood assassins. It's not really a roleplay thing so much as an immersion thing. For my elder scrolls play style, it's weird to adhere to a bunch of conflicting codes depending on who's handing you your quests, thematically speaking.
So I'm left with some questions I'm hoping some of you kind folks can answer.
Firstly, am I missing out on significant content if I choose not to join an ingame guild experience like the dark brotherhood? Is it content I will miss as a not-assassin styled character?
Secondly, if I take the starting quest to join a guild like the thieves guild or dark brotherhood, is there a way to opt-out? Is there a story experience like in Skyrim where I can choose to kill Astrid, a murdering cultist sort, instead of getting recruited into a cult of murderers, or am I stuck with just joining up to clear the quest log?
Is there content I can explore in the new expansions without joining the respective guilds they're named for? Can I quest in the new dungeons for rewards without being part of either of the guilds?
Any clarification would help. Thanks so much!
