And had to make the typical post with the "devs please respond" request that any of a hundred thousand people could have answered in-game.
Research time doubles with each trait. The eighth one always takes 32 days (can be reduced with Metallurgy/Stitching/Carpentry). It is intended and to me feels just about right - takes some time and effort, but it's perfectly doable and many people already have 8 traits on several items.
If you post in a 2 day old thread, you are a Thread Necro, and if you create a new one, you are just making another of the same.
You just can't make some people happy.
If this was game was F2play, I would agree it does feel right. But it's obviously a time wall to prevent progress. 32 days is excessive and will obviously be changed in the future with a hard cap on traits only lasting a maximum of 7 days.
I know a few people that have already completed every trait in the whole crafting cycle
