I have been in two minds about a number of changes to FFXIV over the last few months, but these changes seem to be really poorly thought out. I like the current crafting system, it is suitably complex, requires a bit of effort and most impotently makes sense.
In the current system, when you make a piece of body armour, you make the breastplate, the backplate and then assemble the bits together. Its (roughly) how it would be done in real life and you can see the bits on your character when you put it on. The new method is just to throw a bunch of random mats into a heap and hope.
I agree that the sub assemblies should be at a similar rank to the final assembly, but removing them completely is not the way to go. Yes, change the rank requirements, yes, make the sub assemblies a bit simpler if you must, but don't remove them completely. I am also not completely happy about the removal of the secondary skill requirements. As far as I can tell most of them made some kind of sense with regards to the materials used.
The other changes listed, if I am understanding them correctly, also seem to be a step backwards.
In my opinion, one of the distinguishing features of FFXIV was the crafting system. It was what made the game different from the rest and gave those of us who like crafting a challenge. To make something we had to get all the materials and then expend a bit of effort to actually complete it. After these changes it is just like everything else, bland and uninteresting, if we are going this way you may as well remove the crafting mini game as well and make it just get mats and press a button and let the RNG do all the work. All the other MMO's out there do it this way and we don't want XIV to be different.
Also, if anyone decides to reply, don't give me the 'old recipes will remain', that doesn't answer my problems. They will be phased out after a while and everyone will use the simple recipes.
I like XIV, I have played it nearly every day since release. Please keep the current crafting system. Let us work for our rewards, some people like to do this.
