Not needing ballad doesnt seem to be that unusual, i dont think its the top 5% only or something. However id argue tp song is in high demand, double goad does not seem to be enough to serve 5 tp users as well as paeon does (2 tanks + 3 melees or 2 tanks 2 melees 1 bard)-

You can sort of do it but there usually will be some downtime on tp for at least 1 player if not 2 or more.
