Should I just stop playing bard now? (not a rant..serious question)

Barrage got changed and the effect of determination on Auto Attacks got decreased, so even without WM, auto attacks will overall play a smaller role than before.

Yes, but barrage is also better since you can use it while moving. How many bards did I see using Barrage and running around at the same time. I think the change to barrage is actually pretty cool even without the WM.

Also, in my opinion it's too early to talk about determination. You forgot to mention that while the effect of determination on AA decreased, critical hit rate was changed as well. It might just be the same. Instead of doing constant flat damage, you could do less damage overall with your AA but then get the same DPS after doing critical hits. But again this is why I said it's too early.
