Without the passives from each line it'll get up to 60 days?
ESO+ reduces it by 10% (IIRC), and the max passives will cap it at 30 days.
At least it's passive so it happens while you're offline and you don't have to be logged in for it to advance.
But, yes, becoming an 8- or 9- trait crafter takes time.
My 18 9-trait crafters will welcome you to the club (all done before the research scrolls existed... lol)
tmbrinks hit it on the head. Welcome to the road to Master Crafter.
Woodworking will most likely be the first one you will get 9 trait on. With max Passives, it can take about 6 months to a year to 9-trait everything. Each trait known doubles the base research time (6,12,24,48,...) with a cap at max passive of 720HR (30 days)
Blacksmithing & Clothier have 126 researchable traits
Woodworking has 54
Jewelry has 18

7 16day 12day
8 32day 30day
9 64day 30day
Rough math:
9 trait an item with no passive - ~128 days
9 trait an item with max passives - ~84 days
14 item types, 9 traits, 3 slot, no passive - ~597 days
14 item types, 9 traits, 3 slot, w/passive - ~363 days
with research scrolls the time can be reduced significantly but can be resource intensive and relies on a steady flow of vouchers... but can reduce research time in half.
Assuming everything is kept back to back and a research scroll is used once a day, at the same point, every day with little to waste.... it is possible to 9-trait everything in roughly 6 months. Keep in mind that is using ~188 research scrolls per skill line.
It is too early for math, please correct me if I am wrong or terribly off.
The system is a waiting game for those who wish to be a master crafter but makes learning traits a matter or priority and planning for the toons play style you want (as well as unlocking craftable sets that require a number of traits known). It gives those who have put the time and effort into the game some bragging rights and an edge in the market and guilds.
Good luck on the road to Master Crafter. Soon you will be swimming in Surveys, Master Writs, and Vouchers.
