Rhoa mount spirit cost too high given its usefulness?

C'mon. 60 spirit could afford you a Wind Dancer + Herald. Or one of those with a bunch of supports like Cannibalism, Precision etc. I.e. some good mix of offensive and defensive options.

For that you can also ride a rhoa. Awesome, really. It's cute, I love it. And I'm sure you'll sell some amazing MTX for it down the road. And I'll buy them, probably. But:
- It's pathetic offensively - any good tamed beast will be better for like half the cost.
- In fact, being a companion itself, it competes for a single slot with actually useful beasts. Unless you take the Trusted Kinship keystone that gimps your defences.
- You don't get even a minor movement speed increase. SERIOUSLY? Not even a paltry 10% for a "feel good" factor?
- Makes precise movement harder due to TURNING RADIUS. (Movement overall feels good, but the point I'm making is, it's less flexible than on foot.)
- Encourages ranged-only gameplay, which runs counter to your "vision" for the Huntress.
- Yet you don't allow crossbows while mounted.
- Or spells.
- Not being a buff, it denies use of buff supports.
- Heavy stun bar does not dissipate by itself, you have to dismount and mount again to clear it - bug?
- Dodge rolling dismounts you. You'd think you'd want this but it messes your muscle memory. Wouldn't it be better if the Rhoa performed a DASH instead?
- Yet you can't use a travel/leap skill while mounted that would automatically dismount you.
- With it being so relatively useless, I don't understand why it's gated by such a high level requirement.

So, you're paying 60 spirit to not slow down while throwing spears or shooting a bow. And to get heavy stunned and killed.

Am I missing something?

I was excited to be the birb raider too, until i realized that instead of this feathered liability i can have random ahh 40 spirit crab companion that gives me haste aura, stuns, blinds and tanks for me better while not disabling any of my abilities together with wind dancer and herald of thunder. The possibility of getting heavy stunned is a joke too, since amazon and ritualist have no defense options whatsoever and slot machine evasion is all you can depend on, you either get oneshot or not. Not even to mention that all companion nodes on the tree are worthless.
I have no clue what the idea was behind this skill. It just makes your character worse but i guess it looks cool on the trailer

60 spirit: you are immune to melee attacks. very much worth it.

Yea that was during campaign.
Once you get enough damage/spirit the bird is completely broken.
If you get a lot of evasion and acro or even Hyrris Ire you will never get dismounted.
Nothing compares in terms of clear speed
