Quick Synthesis NEEDS FIXING
It is absolutely UNACCEPTABLE that quick synthesis does not take is basic skills available to your crafter.
For example...
MY 50 Goldsmith has 351 Craftmanship and 344 Control. When using quick synth to pound out some brass ingots (lvl 14 recipe) I still get fails! I mean c'mon! Especially when I Have Careful Synth 2 available. I understand there should be a penalty for using quick synth. To me that is grinding out Non_HQ items while I am AFK. Also the fact that doing 3 stacks of quick synth (for base mats) will knock down your down to 0%.
If i'm going to be at my pc anyway I might as well use my 1 key macro to HQ them and guarantee not only HQ but 100% completion and doing 3 stacks my gear is still at around 50%.
SE needs to look at how quick synth works. At the very least it should take into consideration the skills available to me.
