Guild Wars 2

Can an alternate method for gaining Resonating Slivers be added? Maybe using guild commendations, karma or something?
As it currently stands I have the chance to get 1 to 3(and if RNG blesses me maybe 10) from each guild mission I complete on a weekly basis. If my guild unlocks all 10 missions, we are talking between 10 to 30 slivers per week if I complete every mission.
My scribing is just a bit over 200. To make a Fine Scribing Kit it takes 9 Resonating Slivers. Was it planned that we make one item each week?
And yes, it is fantastic they are on the trading post but due to the volume required to level scribing and the painfully limited supply, the demand has the price above most of the loadstones in the game.
Also before you say, the guild should pitch in. The hall upgrade process has for-filled the feeling of contribution for most players. Not to mention that unless your guild detonates a single player to be the scribe, any volunteered resources are split.
The leveling cost is only compounded by the low amount of discoveries for this craft.

Can we please have an alternate source of Resonating Slivers?
