I recently leveled a bard to 70, got him some songs and some aa's and now he's in t6
I made hotkeys to control his songs. Normally I /melody 3 songs for combat. They are:
Slayer's Destiny Rk. I
Psalm of Veeshan
Storm Blade
I normally run: Warrior, Cleric, Bard, Necro Necro Mage in the "Bard" group.. Storm blade, haste and resists added to the pets are pretty nice.
another hotkey for selo's, but that's rare.. usually only used when heading to that far off Ldon
I'm sure there are things I can do differently, but just starting out Resists are pretty important.. for some reason dragons like to aoe, even though we all know that their wings would block the aoe from behind anyway

Just remember, when fighting a mob/boss that Silences to use just 1 song. IIRC if you sing just 1 song, it cant be silenced.
Another thing I do with my bard, since they are pretty weak and usually get rampaged because I forget to turn off songs, I just leave her with the casters.. range is far enough that the songs hit the tank/melee and all is good.
Fading Memories is huge.
Something else that I do on all my toons for AA's:
1) Innate Run speed (yeah yeah. mock if you will.. but I'm impatient when waiting on my toons to catch up
2) Resistance AA's
3) Class AA's (anything that defines them.. for the bard it will be the singing, Instruments, Song Range etc..)
4) Mystical Attuning et al
5) Defensive AA's and Health AA's/Delay Death
Again.. I'm still learning bard as well, but those are the things I've learned thus far.
did I leave anything out?
