First of all, +1 for the Family Guy reference. I really do miss how the show used to be before it came back.
I don't have much to add other than stating "I agree" (except for the bit about play time, I won't get into that), but I do feel the need to comment on tier III stuff. While sometimes it isn't useful, other times it serves to allow for lower risk double/triple meld attempts. As soon as the relic quest was patched in Touch of Rage IV prices jumped through the roof on Gungnir. Went from roughly 200k to 1-1.3 mil. On a standard plate belt a double meld of two ToR III was around 24% iirc, then was about the same as a double of IV for a triple of III. A triple III is usually 4-7 emnity more than a double IV, with each materia costing 75k-110k.
So it does have its uses. One attempt at a double IV amounts to six triple III attempts on Gugnir, even if you factor in the cost of the belt. It's just a matter of if people with the issue you mentioned can get over trying for "perfect" melds because honestly, I don't think anyone will get that IV x5 item we're all dreaming of.
