A simple question, I've been messing around on the Timeless Isle now a bit, but besides some gear-upgrades for alts I never seem to find anything useful for my 'LFR hero' main (ilvl 506). I've seen a few people talk about itemlevel 535+ (?) drops and such and items that upgrade your gear, but ... where do you find them? How do I get my hands on them?
I've read a few sites like Icy Veins, but they still left me pretty clueless as to how to use the Isle mainly as a gear-upgrade zone. (I'm not very interested in rep grinding or vanity items).
