I really like the direction 1.0 was taking after Yoshida joined, from what I saw on youtube. Wish I was there during the transition. Definitely have a lot of respect for the 1.0 players who never lost faith in Eorzea.
One thing I wish they would bring in 5.0 is a more dangerous world with rare things, 1.0 seemed like it was going in a direction where exploring was seeing as something special and important.
