Is couragous onslaught worth it?

[Hammerspace]

I am trying to evualate the couragous onslaught feat.
It is a good feat but the feat tags for the prerequisite feats seem rather high.
For non warrior bards it effectively 4 feats
Multifarious bard
Courageos advance
Courageous assault
and Couragous onslaught.
What are the general experiences with this feat?

Just to note: that is compared to the 3 feats that Warrior Muse Bards get it for.

All three - Courageous Advance, Courageous Assault, and Courageous Onslaught - look like pretty good action economy assistance.

The first two are basically that you can donate one of your actions to an ally. Like a sustained duration Haste, but more limited. Reusable though, so that is a bonus. The third looks even better than that. You are getting a net gain of actions for your team for the round.

Knowing how much characters feel action starved during combat, I would think any and all of them would be quite valuable if used well.

I don't have any actual experience with them specifically, so I can't say much more than that.

The good part of courageous assault and onslaught is that the reaction attack uses the ally's full dicepool.
So hitting and even critting are part of the action.
My party has a rogue, barbarian and a fighter.(and an archer ranger and cleric)(but not everyone can make it all the time so there are usually 1 or 2 players missing).
I recently respecced by bard into getting courageous onslaught and I have had 2 fights with the new build.
I had fun casting harmonic dirges of doom and inspire courage to spurr the barbarian into extra actions.He critted multiple times during that fight.
(I also have eternal composition, so 4 actions per round)

Letting others move or even attack outside their turn can be quite powerful.
We had several encounters where the enemy force would use similar abilities, for example a gnoll sergeant with bark orders (step as a reaction) - really annoying for our melee characters.

Courageous assault, the one granting the strike, does not have any prerequisites other than warrior muse - and is very powerful. Especially for target allies without reactive strike, but also if that would not be triggered in a turn.
Compared to haste i think it is better for most melees, as haste gives another action that has map, usually a -8/-10 attack, while this is map-less and as strong as a reactive strike.

It is situational, for sure, as it means your bard does not have room to cast a real spell - but that may often be the case anyway.

Something to consider is that tt kind of clashes with action compressions like lingering composition or martial performance - but it's still a strong option.
