I haven't looked all that in depth on here but I don't recall seeing anything on resists. Back in FFXI there was a magic number for fire resist which would nullify nearly all damage that was fire based. Now I'm on here, and I'm curious as to whether there exists a number similar.
I just finished up ramparts, and the dragon boss there hits HARD, and its all fire damage. Thing is, I only have about 39 fire resist (limited gear) and can pop a trinket for 50 more. Is it worthwhile to develop a set specific to certain dungeons, knowing that some bosses use nearly all of one element?
