Fact about cyborgization: It really is not worth it for the amount of time/material investment that you put into it.
The benefits of gaining metal limbs and body is that you become partially, but not completely, spaceproof and you gain a basic 25% Melee resist towards all sources of damage based on Melee attacks Eg Brute from anything blunt and Burn mainly from Welders, with diminishing returns depending on how much armor you get on yourself.
Diminishing returns? Well Riot Armor currently protects up to 80 Melee Brute plain reduction. Along with Augmentation, you can only get up to 86 Melee Brute resist, as the 25% only affects the 0 basic defense and is lowered depending on how much armor you put on top of it so that it can never truly be 100.
You are also immune to ALL Chemicals, including anything harmful or helpful.
You are also immune to ALL Viruses, be they harmful or helpful.
You also heal from just welders and cable coil, but that is actually a bad thing and i'll start explaining why now.
The downsides of gaining metal limbs is that you can't be healed quickly by chemicals. You can ONLY fix yourself up with Welder and Cable Coil, and unless someone else is administering them to you, you will be stuck for minutes welding and mending your ass up with how slow fixing yourself is.
Chemicals, in the other hand, act incredibly quickly and stack with eachother. You will see no chemist do a simple patch with only Bicardine as a combat mix. He will add as much as he can into the mix so that it heals him up to 100% as quickly as possible, that means bicard+tricord+DD+Omni+kelo+derma+sypticP+silverS in your most basic "combat stim" patch and, if he's any competent at his job, he'll also add small amounts of Hyperzine, Ephedrine, Crank, Hotline or even BathSalts to his mixes for unmatched hyperspeed and anti-stun that is faster than Xeno Hunters.
Another bad thing about augmentation is that you lose some of your base speed. You are slow as molasses as a Cyborg and you CAN NOT FIX THIS WITH ANYTHING. The chemist will be running circles around you for hours with mixes he can make in 5 seconds meanwhile you're stuck with a subpar armor that can't even protect you as well as it should. Couple this that SS13 combat is ALL about Stuns, if either of you are smart at all, you won't be just meleeing eachother with Toolboxes outside of really desperate situations. You will arm up or at the very least keep a stunprod handy if you intend to fight eachother at some point over any innane shit and the first one to fall is the one that dies most of the time. Even so, if you stack armor with your cyber limbs you can only truly max out Melee Brute Resist, not Ranged Brute/Burn damage sources or Melee Burn based sources such as the Energy Axe or the Upgraded Welding Tool.
The other bad thing about Augmentation is how long it takes, how much it costs and how it definitely requires another dude to augment you to make it faster. It takes up to a max of 10-15 minutes to self-augment yourself fully. That is disregarding parts build time, the fact that you can die very easily when self-augmenting or streaks of constant bad RNG rolls that make you re-do shit. Just the plain surgery itself takes a fuckload of time.
It also takes 45 Sheets of Metal to print all parts from an unupgraded Robotics Fabricator, i've never seen augmentfags even upgrade their own equipment, so by the time they make 2 borgs/1mech and augment 2 people, they already ran out of metal and will cry at Cargo or Engineering for more materials and will start cannibalizing their own department for more of the damn thing. Seriously fucking do some basic R&D, just Materials level 5 and Pico Manips+High-Power Lasers basically makes you save up to 75% of your resources by just upgrading the machine.
With a competent partner you can cut down the surgery timer to about 1 minute or even a little less, but it requires him to act perfectly in every step of the way and is still not efficient.
Compare that with just mixing chems which take less than 10 seconds to come up with basic mixtures and massproducing patches and pills and you start seeing why people call Chemists overpowered.
I will not argue about this and i will fully state that Cyborgization IS faster than Virology, but that's mostly based on RNG and if you roll insanely good you can finish a god virus mix in 3 minutes or even less, but usually it takes a good 15-20 minutes.
Also you are subceptible to EMP as a Cyborg. There are many ways why this can fuck you over because it deals HUGE amounts of Burn damage to your entire body and several Antags have repeatable sources of EMP.
