How to failstack?

I've been trying to failstack on green gear, because I assumed that what I read here (https://docs.google.com/spreadsheet...30Zrcxteq8U2VSa3itdd1eitA8/edit#gid=541890420) that says "Enhancement failstack chance +30% on green gear" means that I should have an increased chance to get more failstacks. However, I have on 3 different occasions now gotten from +12 to +15 in under 5 fs each... Am I doing something wrong? I'm not getting frustrated, rather I'm getting worried because I would prefer to not waste my boss gear's durability... All replies are appreciated, thanks in advance.

 

Best way I found to FS on this server is to FS on DOU TRI + green gear. Its stupid easy to gather shards. +0 to +15 on green is a joke even using the durability button lol.

 

Make horsegear, enchant them = profit. If that doesn't work, get everything to at least PRI and start hamming on them.

 

I just get tons of artisans from the free pearls, make alot of pri's.
then get alot of hards and sharps. which is not that hard.
Getting 45 fs trying to get to duo, is something that happend quite a few times here for me.
