Indeed blunt mastery is deeply flawed. It is not something that can be fixed by juggling numbers in the configuration files. The basic mechanics of how blunt mastery works is broken and always has been. The folks in North America do not have the skills or corporate mandate to fix core issues like that. Only PW Korea has the developers and access to the code necessary to make that kind of change.
Look at it this way: if PWI (North America) took it upon themselves to make this change, and I am certain if they wanted to they could find a developer to do it for them, what would happen to that change the first time new content comes in from Korea? Gone! You can't merge that kind of change.
The only way blunt mastery will ever be fixed is if PW Korea does the change, and they don't read these forums. It would be up to PWI to convince their parent company in Korea that this change is necessary and I don't think either one is all that convinced it would bring in those tactical profits they are so fond of.
Iceyy: Nobody is gonna bother to read thru 7 pages of game complaints to see what you wrote on page 2...
There is nothing at all wrong with the magic/melee blunt conversion itself. What is wrong is how that converfted melee interacts with the melee attack modifiers you add in-game. If you apply magic attack modifications, they add converted melee. If you turn around and add melee attack modifications they compound to that converted melee basically giving you an unfair double modifications. This whole 'double dip' compounding is the problem that gives Templars that unfair advantage - not the blunt conversion itself. It is also the reason why pretty much all of the templar's magic attacks go unused in favor of players squeezing the last dregs of unfair Melee out of that double dip formula.
To fix it, PW has to make melee enhancers work ONLY on melee not derived from blunt mastery. That is not a easy as it sounds and it would take a huge effort on PWI to convince PW Korea it is the right thing to do.
