Creativity is admirable, but big nope on all counts. AoE is not the problem with Apex, and we hardly need a Bane. Raging is one of the few nice things we have going, I wish it were stronger honestly. And doing that would be a better way to give us a steroid than self-BV, which is dubious for reasons well-explored in this thread. And we don't want Barrage to start mis-aligning.
Some people like Wide over Nock, but personally I'm a fan of a 12y cone > 5y AoE any day. If Wide was 8y like Rain, then maybe.
Circling back on the Raging point, buffing Raging is another option on the list of ways they could increase numbers while making the Bard kit reward better decisions. Especially if coupled with a change to a more flexible Apex Arrow.
I remember pre-launch I was really hoping they would have the foresight to make Raging i.e. 20% for 15s or something (along with expecting BL charges and hoping for a flexible Apex), but alas.
