Hi I'm planning on starting a turn-based run and would love to go with paladin/chanter as I did in my original run-trough. I've been doing quite some reading but can't really get my head around how the Herald class work in TB-mode, and which subclasses go well together. In my original run (non turn-based) I went with the Healing Wall (shield-bearer/troubadour) and would really like to try this out again - but is that viable in TB?
