I agree with the OP. It would be nice to have more insight on what the devs are planning.

Additionally, there are obliviously a lot of people that have not played in Coil yet or understand the mechanics. Bards are brought for two reasons, T1 mini ADS for silence rotation, T2 boss ADS for silence rotation, and you need two physical DPS for Turn 4 so it aligns nicely. Songs are rarely sung (aside from FR) because of the -20% DPS. You simply can't afford less damage due to mechanics of the fights in coil.

If they give other physical DPS classes a reliable silence like bards then it would make less sense to have two bards (or any) due to current bards dps. Other classes shine in coil where bards fall behind a bit (dps wise).
