Well, I do not think Ruby's build is anyway bad at all. It's intresting and bard who can cast alot 0-2 level spells and be very deadly in close combat (plus can off-tank if main tank unable to tank or is otherwise occupied) and use breath weapon is big pluss ;). Also blindsight is nifty ability and hard to pass.<br/><br/>It's true that in some sense DD sucks as 'caster' class but if you take class after like 10lvl as sorcerrer then you will be able get ALOT bonus spells in 3-5 spell slots (and so offer flexibillity). Of course you can argue what good half-caster is high level when caster actually finishes DD then I can say it's merely a concept and DD gives caster alot survivalbillity.
