For BRD:

Have a baseline level of proccing plus extra procs from DOT ticks. This will make AoE involve interesting decisions again.

Give me some actual songs to play during my combat cycle. Our current 3 songs could require a cast time (with no target); new buffs could be added; we could sing an insult to debuff enemies; etc. I just feel like an archer with some extra animation flashes, currently.

One gimmick could be buffing nearby allies with our songd only to encourage positioning choices in the raid group.
