As I recall, you stop getting pinks after 47, Aurum Vale being the last spot. Maybe from a chest during a battlecraft leve (unsure if the loot scales in level if you pump the leve level up) as well. At 50 pinks that randomly rolled great stats aren't an option anymore. Just the static stats on greens/blues compared to materia melded crafted gear.

The real 'future update' that'll be a pain is when new crafting gear comes out and we have to remeld everything.
