Is the elder scrolls online plus membership worth it?

I purchased a one month membership when I played ESO.

If you want the DLC, but want to test them out first, it is worth it. If you want crowns, it is definitely worth it as it's pretty much the same price as the crowns.

If neither of those interest you, then it's not worth it.

I don't own it so I can't say for sure, but in my opinion, mostly any game where you pay monthly is probably not worth it.

Is the game itself worth it? I've been considering giving it a shot but I'm really not sure about it :(

I didn't play it until level cap so as far as MMOs go my opinion isn't that useful but I really enjoyed what I played and I've played a lot of MMOs. The quests felt just that little bit more interesting that kill/fetch quests even though that's essentially what you're doing anyway. Being able to steal was a really cool feature.

I just realised you only wanted to know about the DLC though. I played before it went F2P (or B2P whatever) so I'd say it's worth it :p
