Answers from anyone knowledgable would be nice.
1: Are shards still bound to account?
During some of the previous iterations, you could move shards between your characters after creating them. Is this still true?
2: What success rates lead to optimal advancement?
Previously, because of near-unlimited tp resources, people were advancing with 40-50% success rate shards. Is this still the best solution for overall efficiency, or is it simply fastest?
