I don't see how putting accuracy on the bow would be a bad thing. Most people saying that are saying that because they are assuming most bards will have mostly high allagan armor which isn't going to happen without lots of luck. Accuracy is never a bad thing for bard, the main thing is the weapons base damage...But I'm sure someone will say that if you go 44 crit/31 det you will do 00.02% more damage over the course of a fight or something lol. You will be doing just fine if you add accuracy on your novus bow...
