I wish we could opt out of doing crystal tower raids- I don't even fully participate anymore when I see Syrcus tower, lab or WoD.
I've always found it funny buying a new expansion just to go back & play old content so you don't even get to experience your class fully due to ilvl sync for most of the roulettes. It diminishes the experience of new content atleast for me.

I'd rather have a choice & do Ivalice raids & up.
