Just my two cents...
Stealth is not just about dipping. Some of the best combat characters I can recall in Sindome history have been very stealthy too. Same with some fixers/candymen.
Regarding the dip hate/fear, I have almost completely agree with 0x1mm on this. You can and should build with these dangers in mind. I can't build a character with no combat skills and complain that it's unfair combat characters crease/mug me. So I don't understand why players thing that protection against other builds should be automatic and free.
I have played at least three dips and it's not as easy as many want to suggest. There are a lot of ways to work with the current coded systems but I honestly find most of these limitations annoying and catering to players who want to min/max character but still have protections against dips (mostly combat characters but also doctors, fixers, candymen, mechanics and MANY more builds).
I honestly feel like these coded systems that reduce a min/maxed character's exposure to stealth further encourages min/maxing. I don't need to build a well rounded character, I can just complain OOCly and get coded defense built in that doesn't cost UE.
I want to stress that not all players go this route but enough have that such coded protections are now built in. I also don't think it is malicious or bad or wrong. Just a difference in playing stye and OOC priorities.
And regarding RP in terms of dips and other stealth focused characters... This is the same to me as when people complain about the lack of RP when it comes to being engaged in combat and killed with little to no talking to posing before, during or after. I get how it can feel that there is no RP value here but in my experience there almost always is. It's just not focused on you at the moment.
I get it can be a bitter thing but I always try (and it takes real effort) to think about other PC's stories and that I managed to be a part of theirs in a way that was interesting for them.
In a game like Sindome where everyone is the good guy to some and the bad guy to others and nobody to most, I think it's important to set the expectation to oneself that there WILL be times when things will happen to my PC that seems unreasonable, unsporting, unfair, unexplained and lacking in direct RP. It's not usually characters being murder hobos or unsporting dips. It's you being the redshirt in other PCs stories for a bit.
Overall, I'd prefer for a lot of changes like the one proposed here to reduce the handicap on stealth builds and to encourage rounding out character builds. I'd love to see disguise rebalanced to encourage more players to invest in heavily in disguise as they have to in stealth. At the same time, as Slither has mentioned, I think stealth characters can work well enough with the coded limitations as they are.
