would need some pretty awesome rng to get to +15 with those %, especially w/o safe points...

Today I tried to enchant 3 stigmas, one +7 one +5 and one +4, the +7 went down to +4, the +5 went down as well -1 and the +4 went to +3. Not a single of them was successful, only one time the stigma remained the same and didn't go -1.

Al of the trials were done with the gold ingot stigma enchant with alts.

maybe it's just my bad RNG luck...but it seems that it is much worse to enchant a stigma to 9 since the patch.  I just went through 50 stones and (3 stigmas) to take a stigma from 7 to 9..and ended back at 7 at the end..at one point it got so low i used stigmas to enchant cause it didn't seem worth it to go from 1-2...with a stone.  out of all the success and failures i only had 3 remains the same and none greater than 1 on the success.  I can't even imagine what it would look like to get to 15..
