Sorry have to ask how will it stop the lack of Potency runes?
When I decon a glyph I don't always get potency runes and I bet neither does anyone else. In essence it would just give you another possible avenue to get Rune parts from.
All I can say is either find someone to share decon with or join and guild and get what ppl don't want. I share with 4-5 others in my guild and it really helps. Although its not quick I'm about 1/4 through 38 and I have deconned a lot of Glyphs and gone trawling for a lot as well.
For me once I hit 40 and spend the last SP I don't care how long it takes to hit 50
