You've misinterpreted our lack of agreement as a lack of understanding. Everyone understands what you're saying, but still don't agree with you.
Items with special abilities, clear ring and guard helmets it makes logical sense that the intention is for them not to be available. I guess the 'bug' there is that Andy forgot to mark them as unique, but come on you know they are unique. They don't drop as mythics and you already said yourself you can't make things that can't drop.
If you find a bug you have an obligation to report it rather than exploit it. So please use this opportunity to let Andy know which unique items can be done when they shouldn't, and about the ability to 'double mythic' and certain things rather than trying to do as many as you can before it gets patched.
When these bugs are fixed you'll be left with the best items ingame that nobody can ever replicate and you know it, it's frustrating when you play dumb because I know you're not. You know you are bug exploiting. Instead of pretending you don't know any better maybe just don't do it! I hope these items are adjusted when the bugs are fixed.
