Bard Tank!?

[thewrush]

Hi, I started a bard and have been told they make decent tanks prior to 50. How does one go about gearing and using songs to become "The Bard Tank".

Currently, I have a Human Rallos Zek bard with most visible pieces of Cultural gear(+STR +STA, AC). He has a bunch of missing slots but sits around 144 STR and songs bump him up more. He is using 2x 5ac 55HP rings and has around 600 HP at level 20.

What can I do to further my tanking career? I might try to farm some Guardian Armor for him(if that is even remotely sane to do given the drop rates). I don't care about end game blah blah blah boring sit in front of screen for 20 hours for something to spawn, then wait another 2 hours just to engage BS. Just want to approach this class and do something different.
