Maybe a similar merge as to what was done with monster drops:
NQ/+1 = NQ with new stats closer to +1 (5% bonus) to appease the masses.
+2/+3 = HQ with new stats closer to +3 to appease the few.
As much as I thought the +1/2/3 system was a bad idea when FFXIV was first released, I really like and enjoy it now. Especially with 3 alt/mules on a free buddy pass acct to help manage it all. I'll miss the old system, but I know its a necessary change to streamline the game's crafting/itemization bloat.
