When people start bringing up different games having different systems, I really have to hold up my hand for stop. FFXIV: ARR onwards is made from the ashes of the jumbled mess that was FFXIV. We don't know just how much of the jumbled mess still exists. Only the FFXIV team does. Given the time they had to work with to get out what they could for ARR, there's still probably plenty (even if every patch had some sort of fix to those past mistakes). When they say server limitations, I literally hear "we have to go back and see what core problems still exist and see if we can implement it safely without something else breaking." A lot of these other games that have these systems weren't put in post launch. WoW is possibly the only exception, but it also wasn't built on the ashes of a game that was systematically a mess.

My suggestion is, while we can ask for a player error check, simply take your time and read when buying gear. Especially if it's behind weekly lock-outs.
