Independent of any specifics, I'll point out that any buff resulting from a kit change (making AP stronger, or doing something with RA rng, seem to be the two most common asks) could be counterbalanced by either:

- Reducing the potency of song cast damage (they're arbitrary anyway), or

- Making Chain Strategem do something besides increasing crit rate (this is a good idea on its own merits imo, but BRD would need to be compensated as SE seems to be balancing around assuming SCH's presence)
