Grinding

[psu dan]

Was the chance of success decreased? I'm aware of the fact that there was a boost but I've grinded before the boost and I know for a fact that if I tried to use an S+10 on the first grind it would say no chance of failure. During the boost it would be no chance for 3 grinds. Also is a S+10 supposed to be 50/50 at 8/10 to 9/10? I'm pretty sure before the recent boost, I'm pretty sure I never broke 2 S-rank weapons on the first grind using S+9's and breaking 3 others on the second grind.
I was grinding 10-11 star weaps.

Do you have 3* luck today? Luck does effect the success rate a noticeable amount.

I mean it seems lower than (before) the boost.
(Before boost, decent grinds)(During the boost, awesome grinds)(After boost ends, crap grinds worse than before the boost.)

NO it wasn't decreased. If you don't have 3* luck, that would account for the lack of "no chance of failure".

And yes, 8-9-10 was always about 50/50 without a boost.
