FACT Reinforcement success rate increases depending on how many thousands of dollars you spend in tcoins and how many stacks of enriched you have. When you see people reinforcing their equipment +9, +10,+11 I guarantee they are spamming extracts. Although I believe sometimes those stacks of enriched are obtained through shady practices like duping, but regardless I have tried all those tricks with time of day and after maintenance and freshly repaired gear etc etc etc. The only thing I haven't tried was going broke and buying obscene amount of tcoins. Plus some people just have more luck than others, I am unlucky in general. I would probably be one of the people who spends thousands in tcoins and still fail every single one lol.
