Misinformation. Crafted gear - the best rings, necklaces and cultural gear - is very often used on lvl 80s. The rings and necklaces are excellent until you can get Khitai epic, which is a long long grind (ofc if you leach T4 thats something different). Cultural gear is the same. Its more often - dps-wise - better than T3. The big exception is tank gear, for all other classes the cultural gear is very very good gear and can be used a long time.
