How does that quote refer to the skill level at which people can make items? That isn't what it's saying at all. It was in response to the heating/quenching problem, and "making max quality helms" refers to quality, not the type of helms people can make.
Even if that is what the person was talking about, it still makes no sense. If people shouldn't be able to make items with 0 skill, set a skill requirement for those items. Changing the heating and quenching quality change has nothing to do with what you can make, only the quality of those items.
Also, the words "no chance of redoing this fix" make it seem like they won't change it.
The only way I can interpret that is that they made the heating/quenching change to prevent people from heating and quenching spangens, spangenhelms, and the steel full spangenhelm to 300q. Now, I get wanting to stop that. Granted, the helms have no defense values listed and may not actually function as helms, but no other finished products can be heated/quenched after they're completed. The problem is that they fixed a creaking floorboard by ripping up the entire floor. A much better (and probably simpler) solution would have been to make those items unable to be heated. And give them defensive stats. They didn't do this. They could have made those specific items not change quality when heated or quenched, like ingots or stocks. They didn't do this. They changed that property for everything, and refused to reconsider it when players complained about it. If they had done one of the other fixes I wouldn't be posting right now. I'd be playing, and either enjoying my planned IC vacation or making items to give away for an event I was going to do.
If they were worried about the ease of making helms (since they specifically mentioned helms) I should point out that I did a test a while back with making helms. I worked for a couple days to get 120 or 130 helm kits of 300q, and then completed the helms. Not one came out as a 300q helm. At that time I had 35 armor making and 70 or 80 something blacksmithing. Making helms has never been easy, and getting a 300q kit certainly doesn't meat you'll be getting a 300q finished product with 0 skill. In fact, I'd say it's as impossible as it should be.
