I originally wasn't going to but I decided to properly write about this one as it really could be another game breaking change that is being suggested. Whilst I respect that some of this idea could make sense, I'd like to state my point and perhaps even show some people issues or benefits that they may not of previously seen.
Firstly I will talk about the removal of Kevlar and the helmet. This one specifically isn't really very easy to argue a point towards the removal of it in all honesty.. it seems a little far fetched but if it isn't already clear to people I'll just show why anyway. I really hope that at a first look most of you would understand how game changing this would actually be. From experience in JB (unfortunately I don't have access to actual stats) as @Stunningjam previously said the t's probably have around a 70% win rate if you don't include times when the CT : T ration is quite irrational. To suggest a change where T's would be even more favoured seems quite absurd at a first glance. (perhaps just to me)
The rules that are currents set are efficient for the most part when concerning the freedom that t's can have without them being straight up killed for slightly disobeying. To change the Kevlar on the ct side would make the current system of being the second shot one that could not work. Due to the aimpunch the would put the ct's at a huge disadvantage and unable to punish disobeying t's. When concerning a pistol in the t's hand this becomes quite ridiculous as ct';s are unable to KOS a T with a secondary weapon without asking them to drop it first. This means that when a T disobey's this and opens fire with his secondary he will be able to get the first shot. This may not seem like an issue relating to Kevlar as the T would be getting a first shot anyway, however to those of you that play fairly competitively on cs go (I'm not talking JB, perhaps MM or in a team playing pugs etc.) you would understand the difference of being the second shot with and without Kevlar. The aimpunch makes an insane difference that would destroy the ct's current game.
Another point that does perhaps not apply to everyone with be the realism that we want on SG. In a gaming environment I would personally say that I'd much prefer anything that enhanced the gaming experience and gameplay over anything that made it more 'realistic'. Although, if you consider a real life prison where the prisoners somehow have access to knives or sharp objects for the CT's to not have some kind of protective clothing just seems inappropriate. I don't consider the realism an important aspect in these servers, however if any of the higher ups have a want for realism then this point my apply to you.
The biggest issue that I can see with Kevlar (among the many smaller ones that would be too much effort to comment on) would be knifing from the T's. As everyone understands the T's start with a knife and generally most T's will attempt to bend the orders that they are given as much as they can (which is of course fine) . With things like freedays T's will get as close to the CT's as the can to make their job difficult and/or uncomfortable. If the Kevlar was removed a T would have the ability to left click once and right click once which is the amount it takes to kill someone with no Kevlar but full health. With the CT's current inability to do anything vs a player with a knife without a warning shot (unless they are doing something that can be KOS) to be dead within a second just become of the Kevlar removal is just crazy. I think the way that the servers are right now with the warning shots is good, but removing Kevlar will crumble many of the rules that we already enforce.
So if Kevlar won't be removed the options are then to only remove helmet or to keep it the same. I respect that there is slightly more of an argument with removing the helmet in comparison to the Kevlar and the helmet, however I do not think this should happen either. With the main access for the T's to rebel with being the USP-S, P200 and Glock on many - but not all - maps the USP-S and P2000 will become a one shot kill to the head and the Glock will become a one shot from a shorter range. Seeing as I stated earlier that CT's can't actually generally kill T's with pistols straight away as they tell them to drop them, for the CT to be dead before they could even do anything would be ridiculous. Having a few T's have access to the ability to just straight up kill anyone they want from a lower populated CT defense with just one click and some good aim is just going against the whole gameplay aspect of the skill of rebelling.
This would also cause CT's to play much more defensively, perhaps camping behind walls and on catwalks all the time. It would slow down the current gameplay that we have and make delaying become much more apparent. However this is only with the smarter or 'more experienced' CT's; other CT's would simply just lose round after round bring the current T win rate to a ridiculous high.
As for the point made in the original post to do with doing over 100 damage but the CT staying alive, I can understand the frustration. Perhaps the servers registry isn't perfect, I experience issues with it frequently - as for whether that's me being in Europe or because of the plugins I will not know - but the server is 128 tick and the best that it will be. This CT may very well of taken damage from you earlier in the round and went to medic before you then shot him again, that is the most likely cause. However if you are certain this wasn't the case then it's simply a glitch, but you point doesn't have any logic towards your actual thread. Kevlar or no Kevlar would make no difference to whether or not over 100 damage counted or if the server was able to pick this up. I'm not necessarily saying your situation didn't occur, it just has nothing truly relevant to the removal of Kevlar.
I posted this as I feel like doing something like this would just make me stop playing altogether as it destroy's many fundamentals in the game that I honestly play for.
TL;DR: This removal could break the game or at minimum worsen gameplay, please, do not even consider it.
