I feel like this change impacting skill builds is a great thing - as you mentioned it makes it so that priests need to decide what type of play style they would like or prefer. It does mean warriors may lose out on some accuracy depending on the build, but ultimately it makes the Priest deal a bit more damage. Worth the trade off IMO! But again that is not to say that all Priests would chose that full solo or semi support build.
At this point I think it should start being tested in Tespia. 😉
