A long long time ago, I decided to level smithing, and invested time into it and expected something back from it. I got a decent profit synthing haubergeon+1s and a few other things, and I was happy with my investment paying off.
Then there was a very long period in which crafting was neglected.... not many new gear synths were added, and most synths that were popular were for salvage mats. The benefits of being a high-level crafter around ToAU/WoTG lessened more and more.
And then came a slap in the face for people that spent millions of gil and/or many hours leveling their profession to a high level- Synergy
The basic idea of Synergy I do find sort of cool- combining the skills of multiple craftsmen together to make something better than the craftsmen could make seperate. However, this isn't all Synergy was used for.
Most of the new synthesis since Synergy was added have been Synergy ones. Yes.... some of these require a high-end level craftsman in your party standing next to the furnace, but there are only a few synergy that take two crafts above 60.. this means there are many synergy synthesis that could easily have been non-synergy synths, or could have at least had a non-synergy equal synth added as well. Due to this, I'm finding myself not using my blacksmithing at all anymore... If I wanted to use it, I'd have to level synergy, or find a synergist.
And I hate using and leveling synergy... It uses one of FFXI's (and FFXIV's) biggest weakpoints, the clunky NPC interface. I've tried to level it, I've tried to push through it, but its boring and I refuse to try it anymore. I'd much rather not touch synergy again than having hopes of making my blacksmithing useful again.
So since synergy has been added, crafting has been ruined for me. Every old synth is becoming obsolete, flooded, and only a few have a profit now. This happens while Synergy gets nearly every new synthesis that is of any use whatsoever. I could even understand of most armor being synergy, but its not only that, its EVERYTHING. Even new ammo is synergy only, even though the other crafting requirements may be minimal. I feel like this is a huge slap in the face to non-synergy professions.
The only thing that could really be done to make this less annoying is to make non-synergy equivalent synthesis for synergys that dont require 2 60+ crafting levels.
