Misery's End, Blood Letter and Heavy Shot all on 1 button is a huge help.

I mixed up DPS Buffs between 2 buttons. One button is Internal Release and Barrage (since they don't directly affect damage) and then Blood for Blood, Hawk's Eye, and Raging Strikes on another.

Don't let people tell you macros aren't good for bards. The ones that help you use your procs when they're up without having to watch your bars help hugely with raid awareness and the ones that condense all your buffs that do essentially one thing help a ton on saving room on your hotbar.
