Its more important that they actually fix Covenant abilities and tuning them than classes atm. Class Changes won't happen much from now on. And tuning classes is way easier by just tuning numbers up and down while Covenant abilities is something they still try to fix, and even change like they did today. Making them more interesting and balancing them somewhat seems to be the prority now and thats a good thing imo.
Since Class reworks and thus class changes is kinda too late to do now(even if I would see some changes) reworking or changing a Covenant ability is a much easier task at this time. And since the Covenant is such an integrated part of the expansion and players having to choose one at the time its dire that those abilitites actually works and can give players something engaging to play with.
