Please don't force us to do tradeskill writs one tier lower than what we are -- even at a x0 level. If I want craft items one tier lower than I want that as an option.
I have seven crafters all the same tier (plus an 8th @ T7) which makes harvesting and storing raw resources easy since they all use the same tier. If I had to harvest and store multiple tiers worth of resources I would have to do some serious housecleaning and get organized. We don't want that!
