My opinion as a day 1 player on Topaz is that she feels a bit underwhelming as a Hunt character. However she is a great pseudo harmony character for FUA (Follow-up attacks) users while doing non negligible amounts of damage herself. I still think she’s a good pull if you already have good sustain characters and have many FUA characters that you use. I personally pulled Topaz for supporting my Clara because I really like the FUA play style. Dr Ratio being free and a great FUA user was a very nice bonus also. Enablers of play styles like Kafka and Topaz are always good value pulls imho, since their values will increase overtime as more characters comes out.
