Started this a few days ago again on Moogle (EU). Haven't played since Open Beta/First Month so I figure I need to catch up.
I also don't have the expansion but my FC says it's not necessary until 50.
I really like how it's not changed much in Early game so I can follow the steps I did before. Only major difference is there are not many people in the the starting areas (but still a decent amount of new players). No more lines in front of the sword in Central Shroud either.
As in the past I am putting an emphasis on the gathering/crafting jobs instead of the combat one (CNJ in my case). I really like the idea of gathering and crafting all by myself, without spending much, preparing for future combat challenges with great equipment and potentially making a lot of money. I am aware that this is way slower but I am in no hurry. Besides, it's also kind of relaxing.
We'll see how it pays off and how long I'll stay.
