Rav Damage (Armor Piercing) and that beno itself
It feels wrong because: Heavy armor is just straight up useless against this caste. Rav already is immune to fire (expanded in "case" below), fast and heavy armor doesn't mean shit against even mature Ravs. At 100% health you can reliably die from two slashes, one slash and your bones break like matches. No beno should be able to break a bone of a marine with 100% health and heavy armor with one slash, otherwise there is no point in wearing one. Rav is the second most broken beno after boiler right now. Just like boiler, he has no counters besides SADAR, his "strain" is just straight up upgrade and now he don't even have to aim his slashes with that brainless aiming assist. He has enough HP pool to survive multiple flechette PB's, he can take those needles like a heavy drug addict. Rav is simply Jack of All trades, but instead of being OK in every situation, he is Perfect in nearly every situation.
In short: Rav doesn't have to be carefull, he only needs to consider retreat from SADAR spec. It's gameplay is brainless because:
a) Speed b) Immunity to fire c) HP and armor too high for a caste originating from Runner d) Strain that is a direct upgrade e) Too much damage/Too much Armour Piercing
Armor and claws.
It would be nice to have: In addition to nerfing Brainless Rav gameplay there could be added special abilities encouraging more tactic and thinking for all benos.
What I mean by that: "Claw Stance". Simillar to Warrior/Defender Crest stance it would be something that beno has to toggle. Deflaut "Slash" would be accurate and fast (the same as normal slashing we have now), but easly deflected by armor. Secondary "Pierce" would be less accurate, slower, but it would be much easier to penetrate armor, but easly dodged. Dodge chance would be determined by victim max speed.
Thanks to that both heavy and light armor would become viable for different reasons, where benos would have to pick their targets instead of blindly slashing while aiming at head (because no matter the PFC, their helmet always have the same medium armor). Speaking of aiming at head: Introduce Heavy and Light helmets. Light having more storage space, while heavy would lose all for added protection (or even something like reducing vision range from behind).

Damage Immunities
It feels wrong because: It's outright stupid for one side to have total, or nearly total 100% immunity to certain weapon of opposing side in multiplayer game.
With addition of acid sprays extinguishing flames, there is no need for any beno to be fire immune.
Queen explosion resistance is about right, she is important and benos can't afford to lose her in one nade stun, yet the keyword is "resistance", not 100% immunity like she and Rav have against flames.
Let's add 100% immunity against neuro spits, acid spits, railgun and boiler gas to all specs. Let's see how this is fair.
{Neth: this won't be resolved or addressed in armor rework, also way out of scope of time}
Beno Sanic Speed and HP visibility:
It would be nice to have: Xeno lose speed just as their health is decreased. Xeno sprite changing when they are hurt and badly hurt.
