To be very pedantic, it's not a complete robot. It still has an organic component.
Deathclaw with no posibility of using range weapons only swords/claws/iron fists /hammers(but with some crit chance add for melee) and of course special armors develop only for they race.
Cyborgs to have the ability to use implants and make implants with the technology known only by them.Even a posibility to upgrade a certain part of the armor and sweapon.
Androids can have some mutation abilityes for range weapons like acuracy and melee combat , self buffs like agility/parry/run speed /sneak /fast atacks (best stealth killers and best assasins)
you shuld know that Fallout mmo will got the place betwin f1 and f2
As a fallout babille "reader"as you say you are you shuld know that Fallout mmo will got the place betwin f1 and f2 so deathclaws can be in with no lore problem.
As for Cyborgs /Androids alot people agree with having those races.A mmo with only 3-4 races will not apeal to alot of gamers and will make it very simplistic in this matter.
In fallout tactics we got all kind of hybrid classes like robots etc.. and they were very cool and not with "balance "problems as you state.
Stick with the thread "For V13, what race would you be and why?" and not what races you dont wana see becouse no one realy wana know what races people dont want to have in v13.
The only plausible ones I can see are humans from different starting places, but having the same race advantages and disadvantages
I can really see Mr. Handy or Protectrons becoming sentient. Just because Protectrons may not be "cannon" to hard-core fans who despise Fallout 3 doesn't mean they're not freaking awesome.
Editz0r: Robobrains could have guns, right? I guess it's possible to forge them into a class if you really wanted.
