I'll chime in here, I've been a point of contention for some people regarding my love of bard tanking. I've tanked N and W HS with groups with ease. I hit 3.5k HP and 150 MR in a basic suit of various Imbrued and odds/ends. Granted N/W HS isn't much of an accomplishment I generally end up tanking, ccing, and splitting my own pulls with much success I do not think I've yet to had a wipe in any of my groups (and these are quite regular). The thing about tanking outside raids is that you need to have a high hp pool and magic resistance esp with a cleric. A cleric is more mana efficient with complete heals the higher an HP pool on a tank is. I've also been in for reets juggs and tanked juggs without an issue.
TL;DR Bards generate insane amounts of threat, enough that an epic SK can have trouble pulling of a bard who is trying. High HP and MR make a bard just as tanky as most other classes, but will never tank in raids nor is there a need for them to. A bard can bring a well balanced tank that gives mana song, CC, AS slows, single pulls, and insane threat gen.
