After a little research on this, while you can not spirit bond iLevel 70 gear
Yes you can.
Nice video, but a few big issues.
#1 Gear slots don't progress at the same rate. Most people know this. This is easily seen when getting a full set of gear for crafting/gathering or even the 4 pieces you get for your 45 AF quests on a DoW class.
#2 He's developing a theory of HQ in X slot going faster qs definitive proof when comparing a NQ in slot Y. No; if you're going to compare you need to do it in the exact same slot and record the same number of kills. If you're going to test something you need to eliminate variables. Randomly comparing different slots with NQ and HQ gear doesn't mean anything really when they don't naturally gain spiritbind at the same rate anyway.
#3 Like he stated materia helps. What I would have been more interested in seeing (as SE's already confirmed this) is just how much materia helps. If you have a buttload of cheap tier 1 types, do you gain more for forbidden melds? If the gear has 2 - 4 slots, do you get more filling all slots or does putting in only one materia cap out the bonus?
#4 He mentions the spiritbind equipment but barely tests it. Killing 12 enemies doesn't really mean anything in the long run. Like any serious tester you need to focus and do a big sample set instead of killing a handful of enemies and dismissing it. At the *very least* there's no excuse to not use the Meteor Survivor ring since that's +3 in a single slot; the +1 slots I can understand not using. Edited, Oct 17th 2013 8:34am by Viertel
