Even my fifth level 80 has blacksmithing at 445, so I'm personally not really feeling that getting to that point can really be seen as very tough. If you, or I for that matter, want to get to 450 then we have to put in the time and effort. It's not about us hating you, it's about you making the effort to do what is required if that is really what you are wanting to achieve. There's a vast amount of people with 450 blacksmithing and sure those last few points may have been tough to achieve in some cases, but it is achievable if you put in the time and effort.

If you do not want to do that, then you might want to really think whether 450 blacksmithing is really what you want now because we are aware of no incoming changes to make this easier until after Cataclysm releases.
