I think they added the tomestones and the mythology ones due to how pleased everyone was with the Gurada fight in 1.0 vs the Ifrit fight. (those who actually won). Doing the content and being able to trade what you want for items was fun. This is vs running Ifrit 40 times and come off not having what you want.

I believe luck content is not fun, but I also agree more variety is needed. All MMOs are a grind, a well designed MMO does not feel that way.
