I guess, but I would only see it as a sacrifice for low int or gifted champions, if tagged with say first aid, which is likely, 200 is easily achievable along with a primary and at least decent first aid.
No special stats have to be sacrificed to sneak, so the non sneak and sneak melee special builds could end up very similar anyway.
Rocking a CLC or even fire gecko leather as a melee sneaker (which is easily doable, albeit expensive, but expense becomes relative after time anyway, especially when clanning up) definitely doesn't put you at an armor disadvantage against anything less than PA, the main combat disadvantage is the sneak penalty timer, which a good melee sneaker will generally bypass by getting one or two shot basically insta kills and taking advantage of bloodthirst, sprinter or voodoo, or more likely, all at the same time (again with the extremes when it comes to sneaking and melee combining here), along with some kind of tankiness (even just high end and a couple of specific critical resistances to ensure escape in most cases).
Gahh, me and my textwalls, I can't help myself i'm sorry.
It just seems that a lot of extremes in the game are culminating with melee sneakers (highest alpha damage, best speed, invisibility cover to close range etc), almost all in the positive for them.
The last thing I personally want is for any build to be "nerfed" out of play, but if, as I was saying before, the extreme sides could be adjusted or re-calibrated in some way, as has been done with other "extremes" in game.
Hit and run comes to my mind when I picture a melee sneaker, but one hit kills (or two very fast hit kills) wasn't what I was expecting, I mean "properly" specced melee sneakers are explosive, it can't be denied, as it can't be denied that greater numbers help against them because they are the very definition of rambos by design
Bleed is perfect for hit and run in my eyes, a single (still high damage, just not explosive damage) high AP hit that applies a horrible bleed (boosting sprinter for the high AP hit) which in a lot of cases will cause one to die unless treated (boosting bloodthirst from a distance in theory, if they die to your bleed while you are stealthed right, which could be extremely useful), and even if treated, you are forcing defensive actions (doc and FA), while potentially getting away much easier. This also still leaves sneak melees with great potential for mopping up fleeing foes and small unaware groups/loners as per usual.
Makes sense to me anyway. The big dude with the big machete (or supersledge/powerfist ect), taking no effort to be hidden should definitely be the more "explosive" (high alpha strike) one in my eyes (if built to maximise melee of course), gives more reason and incentive to focus down melee tanks like this (pulling dps off team mates is a quality tank trait too) also great and immediate consequences (one or two hit insta kills) to the people who choose to ignore the huge melee dude closing gaps and running through the open etc.
Fuck i'm an opinionated asshole, so much text >.< sorry guys.
