What is the point of bard?

Ok I really have issues with bard because I like the idea of playing one but I am not the kind of player
that dual classes melle with magic, and wearing robes sounds lame compared to armour but I lose spellcasting (usually go for the mellee). That said the bards song does not seem very useful other than balancing out morale.

in the description it mentions being a jack of all trades also and having no pick lock annoys me as I am not fond of picking pockets when everyone becomes an enemy if you fail.

So please convince me why a bard is even remotely useful.
