Questions regarding Host Armors

[Snake Eyes]

I've been designing a few HAs, but what hasn't occured to me is, 1) how do you feed these things....Example is that they are like a potted plant with no mind of there own, but under the each of the Metabolisms, it says that the pilot 'feeds' his/her Armor, for instance, the Herbavore Metabolism mentions that it frequently munches on leaves, grass, and other vegetation, does this Armor do this as a mindless cow, driven by instinct to eat, or is the pilot in the suit while its feeding?

2) Under the Super Bio-Regeneration, it says that an entire limb, (arm or leg), is regenerated completely in 4D6+12 days (this is 2-5 weeks), now it says if the pilot's limb was also severed, the Super-Regeneration will completely restore his/her limb....So, a pilot has to live in their HA for 2-5 weeks just so they can get their limb regenerated? or else that limb will be missing permenantly? So how does the pilot eat, bathe, etc.

for types such as Vampire, Herbivore, Carnivore adn the one that eats rocks, they got mouths. The pilot can either be in it and just eat with his hands or he can drop it off at the feeding pools for bio-tech

Of course this is the basis for a long time question about the mental sanity of Host armors pilot. The host armor is quite TOO confortable, and at some point come natural thinking "why i ever need to get out?". And when you're forced out of it, because i don't think inside great houses people are allowed to go around in HA, how shocked and traumatic could it be.
Also one question. If you pass 98% of your time inside an host armor(essentially everytime you have to go out of a great house), and you've to eat stone, or eat raw meat or worst blood, what is exactly the difference between you and a Biotic(vivat Biotics!)?

Think of the Host Armors as living medieval plate armor of the noble knights.
Dreadguard however are rarely seen out of their Host Armor occording to the book.

I would like to see a buyback or merger option, where you trade back an aspect like a gore cannon for half the points, just leave it in the gene pool for a few day and have the armor reabsorb it. Could come in handy when new abilities come out in future books that you just have to have and when you change your mind on theme. This could also be used as a penalty by the warlord for any number punishments too. I had the wings, but a few levels later decided I wanted the organic thrusters instead, so why keep the wings.

I would allow players to "buy-back" features completely if they did not want them anymore.
If the feature cost them 30 Bio-E, then they can get back 30 Bio-E later on by deleteing it from the genetic structure of the Host Armor, etc...

Nothing wrong with allowing a player to to this. it will not unbalance the game/setting.
