I have maxed-out grand master stations at my house. Took me about eight months of effort to get enough writ vouchers and gold to complete all sets. I'm most definitely not runing large guild (or any guild), just really like collecting things.
So after nine months since i started playing ESO and worked my way to achieve grand master crafter and having my first grand master table, found out obtaining sets and feeding them to the crafting station require the attunable version,
as frustrating as you need 250 writ tickets for each attunable for each set per table, that is 80,000 writ vouchers to complete all sets on 4 crafting tables, I'm sure lot of people finding it excessive system to be able to craft sets from your house.
it would be much simpler if attunable tables can be purchased with gold or having it as tool to be reused, a system that make sense and doesn't push players away from.
I did this last year. Bought some stations with vouchers and some with gold... 10s of millions. Wasn't cheap but I got it done! I like it!
At the end it just a Video game, if it was really intended to be limited for large guilds that hundreds of players participate i would say make GMC purchasable to only Guild masters,
but since its available to everyone i dont see the need for one player to stress grinding for it, i'd rather do any other fun staff in the game as i completely disagree with this logic.
