Why take feral combat training?

So I'm GMing a campgaign, and my Aasimar monk has finally getting close to high enough level to take angel wings and then metallic wings. I was certain when I read about feral combat training that it would allow the monk to add these two attacks to her flurry of blows. However, I'm now reading this is not the case.

I sort of want to houserule that it does work this way still. Actually, I sort of just want to give the monk the ability to use these natural attacks. I don't see her 14 strength flurries ruining anyone's day right now, and I don't really see why the monk who has natural weapons should be limited any more than the TWF ranger with them. (on this note, I've already ruled that her enhancement bonus to movement will apply to her natural flight in her natural form as well. All in all it's a set of rulings that I don't really get.)

BUT - I do admit I don't really understand the purpose of feral combat training in monk builds right now. So I wanted to ask all you fine people to explain to me what I would gain from using a natural attack in the place of a weapon for the sake of a thing like flurry of blows. I can see it being useful on those types that want some more damage or multiple hits with a single natural weapon that has a particular effect in addition to damage, but is there more I'm missing out on? On that note, will allowing my particular house-rule have unforseen consequences for my character?

Alternate DR types for piercing/slashing is one such answer.

1.) Flavor. You want a Monk that claws things at lightning speed, use Feral Combat Training.

2.) Certain abilities and natural attacks are better than the Unarmed Strike, due to a number of factors. For example the infamous Monk/Druid T-Rex of doom that has a gigantic number of dice and can flurry with it. Likewise a Dragon Monk that flurrie swith his Bite? Woof.

3.) Different damage types. A Bite counts as Bludgeoning, Piercing, AND Slashing. Pretty good deal for one Feat.

You don't really use feral combat training in monk builds... they're used more for natural attack builds that dip a few levels for Master of Many Styles Monk. Being able to use feat chains like Dragon Style with natural attacks can be pretty powerful.

A character that use may want to use Dragon style with his Claws, Or snake style with his Bite.
Imagine a Half Orc Druid in Behemoth hippo Form snake styling with his bite:)

Feral Combat Training is for druids, not monks.

Being able to use Dragon Ferocity on your claws for a pounce-rake build is a a better deal for 4 feats than most combat chains. Being able to use style feats with your slams as an elemental also has potential.

It's mostly so that you can use your natural attacks in place of an unarmed attack in a flurry using whatever damage is higher between the two(or if you are substituting a natural attack for the free grab or something in a flurry), or so that you can enhance your natural attacks with the monks unarmed strike - aka the damage.

It also supposedly makes all of your natural attacks a Primary attack, so they lose no attack between the set of attacks if you're going all natural. The Octopus for instance, 1 Bite attacks and 8 Tentacle attacks. You can just do a multiattack with just tentacles for a total of 8 attacks at the same static attack value as the first one. You can then use your unarmed damage for it. I'm not sure how true this is... as it still doesn't make sense to me.

So here's what I've gotten here:

- It's not really a monk thing, even if it allows flurry. Really, it's for people who want to use style feats with their crazy alternate forms.
- For this purpose, it's really good. Like really good.

New Question: Would letting the monk gain access to those secondary attacks be problematic? Should I even require feral combat training for it?

Monks are pretty pitiful in terms of damage. I'd say give em their extra natural attacks under your houserule.

I dont think boosting the monk is problematic. The feat will not help you adding them on top of flurry any more than any other feat.

Okay: I'm going to just give them if the monk really wants to spend that many feats on them. It is a lot of feats. They can take feral combat training (and by default weapon focus (wing)) if they want the wings to have the monk damage dice. Thanks for the advice, friends!

It also supposedly makes all of your natural attacks a Primary attack, so they lose no attack between the set of attacks if you're going all natural. The Octopus for instance, 1 Bite attacks and 8 Tentacle attacks. You can just do a multiattack with just tentacles for a total of 8 attacks at the same static attack value as the first one. You can then use your unarmed damage for it.

Where are you getting this from? It doesn't state anywhere in the monk unarmed strike class feature description that you get a Primary natural attack, only that:

There is no such thing as an off-hand attack for a monk striking unarmed. A monk may thus apply his full Strength bonus on damage rolls for all his unarmed strikes.

And that:

A monk's unarmed strike is treated as both a manufactured weapon and a natural weapon for the purpose of spells and effects that enhance or improve either manufactured weapons or natural weapons.

You take Feral Combat Training: Tentacle. I think you would still get the -5 penalty on tentacle attacks, but only in a full attack, even without using your bite attack in conjunction with your tentacles.
