Depends what you're doing. If you're just solo kiting then your armor doesn't matter. I mean honestly, your armor doesn't matter much in the first place as a bard unless you're purposely tanking stuff. The breastplate gives a chunk of hp though.
But I farmed all of mine when I was levelling.. every piece. It gave me something to do, and it was fun doing actual quests and earning things. I wasn't breezing through levels or AE kiting or being power levelled, and it didn't get replaced until I got lucky with some deals for Koada'Dal armor around level 50. If that strikes you as fun, go for it, if you're just gonna level super fast and min/max just skip it.
I miss when all the bards were blue and green.
