Great constellation, the only bad part about it is splitted flat physical damage. Those 6 and 12 damage are already very small, and we all know what does that mean for physical builds: they do nothing, practically.
That’s pretty ironic, too - every build can benefit from physical damage BUT physical ones.
Example
2900% physical damage and rank 26 Cadence (500% weapon damage):
6 * 30 * 5 = 900 damage. Couldn’t probably put a dent on a tin can.
Now, if we merge it with 12 damage from the next node:
18 * 30 * 5 = 2700 damage. That sounds a lot better.
On stuff with way less %WD that flat bonus will be still kinda worthless, though.
So yeah, please at least merge those 6 and 12 flat damage - however you see fit, of course.
