Hiho,
many Engis have spent thousands of gold so far only to get the random procc recipes like Synapsesprings.. for me as a mage the most important recipe..
I also spent lots of time and money to get the recipe but i didnt got it so far.. an now i read that at skill 525 it is not possible to get new recipes when u produce some engi stuff..
Blizz are you serious? They fix tons of bugs.. some not very important things.. but they are not able to fix some important profession mechanics like this..
Well.. i hope they will fix this very soon..
so far.. greetz
