Your WL's opinion is pretty much why I quit playing at our church. Yuck. Piano on top of everything.....the last time I played we did a couple of Lincoln Brewster songs and you could only hear the piano in the mix, no electric guitar . That was the last time I played. Drums and Bass should be at least as loud as the vocals and guitar. Piano and acoustic should be background unless the song specifically calls for them to be in front. You should always be able to feel the kick and the bass.
