Difficulty of normal content.

[Deslyxic]

It's optional content. You dont need to do it lol. If you cant do it, come back when the next expansion is at level 110 and beat it with a couple bodies (or do what most of us warriors do, try soloing it at the new cap). Level 10-100 is your "normal content" or casual if you will. Anything beyond that after cap is either option or not necessary to need doing (unless yoship himself specifically says you need to do x fight to be able to access the next expansion-- similar to what he made everyone do with crystal tower series and Shb). Casual content is all your npc trust dungeons. Gathering, crafting, fates, among other things.

Oh, TY very much, I forgot the "it's optional content" comments. I ignore those too, already said why.
