One downside of using a 3rd party to host media is when it shuts down like gyfcat will in September, it will result in a lot of broken links with media forever lost.
Self hosting has less chance of losing the media at the cost of having to pay for media storage.
As a new website, I'd definitely prefer kbin or Lemmy to just focus on the core product and not self host media yet.
Overall, I've enjoyed it. Some people probably criticize the combat being too easy or how quests boil down to either fetch and run from point A to B.
I didn't really mind how it played out though. I'm not great with action games, so difficulty was perfect for me. I'm also a fan of FFXIV, so I guess I've grown accustomed to the same style of quest design.
I do agree with how narrative feels slowed down due to some of the quests.
