I was wrong. It's even worse than I thought for most people.
Average Tier 6 reward for players other than the top 10 is 9 salvage. There are 4 different items, so that means you are averaging 2.25 salvage of each per raid over time. Let's say you occasionally get a full one, so let's bump that up to 2.5 of each salvage per raid.
Even a good guild (not meaning an all-whale hard-core guild) 3 days to do a Tier 6. Assuming they immediately start new raids constantly, you are going to get in 10 raids per month, so 25 of each salvage per month.
So I was wrong, it's actually TWO months per furnace per person except for the people at the top who are likely there because they already have them.
That's 6 furnaces a year.
Nice reward system.
