I have a question or two regarding mid-range (40s) Bard. 1) Should I be using Quick Nock for AoE? If yes, is there an ideal number of enemies for it (i.e. only for 4 or more, or w/e)? At the moment is the only AoE skill I have, just not sure if I'm meant to be spamming it for big pulls. Also if yes, should probably be keeping Straight Shot up regardless, Bloodletter/Misery's End as available? Do DoTs take priority (set up on everything before Nock spam)?
2) On DoTs, generally ideal to set those up first/early? With buffs as available for extra kick, I've gathered. I've only got venom/wind so far, sometimes end up ignoring them, but starting to see how the group can benefit from those being up as much as possible.
Also, Straighter Shot procs, does the whole holding them for certain points in rotation only really come into play later? I keep reading this is a thing, but sounds like only once you've got WM shifting your style or something.

(I imagine at this range it's not super important, as long as damage is being pumped out regardless. But I figure if I get the fundamentals down, later elements will come more naturally)
