A common question on the forums for people new to spellcasting classes is, "What should my spell list be?" I figure a good way of answering this (instead of answering the same question over and over) is to have a page on wiki with some commentary as to which spells are "must-have", situationally useful, or should be scrolled instead. Presumably, someone with this question in the future could do a forum search for Cleric/Favoured Soul/Sorcerer/Wizard/Bard/Druid spell list/selection and it'd pop up this thread, which would link them to the wiki page here.
I've made a first draft at Divine/Arcane commentary, but have not played Bard/Druid casters seriously (apparently Earthquake and Mass Regens are great... that's the extent of my knowledge), so if any experts in those areas could edit the article accordingly, that'd be great.
