I don't like that weight limit. I would prefer sneak mechanics as they are in FT. Simply metal armor = noise. Leather/kevlar/environmental stuff = less noise or non. Same for weapons. Huge BGF in hands can make it harder to hide yourself (if you are not hiding behind that BGF) but weight limits really sucks and imho only active slots should count.
We have to look to the effect of this change. What kind of player class we will create and think, if we want to support this consequences. I think that any big gunner dont need to raise his fight ability in fight by sneak. So aim sneak ability to small gunners with SMG weapons, maybe with assault riffles. Any biggunner dont want to reduce their firepower, most of them dont want to slow them in the fight, so why add this very usefull ability?? This is totaly nonsese, if someone wants to at least balance the game.
If you allow to sneak only to players using smallguns, with addign special perk to some guns, like i described, you will create new "class" of fighter, usable in the PvP, so now, after 9 months, we will have 3 combat classes, hurray, instead of 2. The fight will be more variable, the sneaker will never do big constant damage like biggunner, but they will be able (in night/day raining) to ambush enemies.
If you dont set weight limit, there will be many player parasites, not fighting bluesuits, stealing the loot on the ground masivelly, with small (smaller than now) posibility to stop them. Is this the purpose of your non weight limit in sneak, Sius?
Devs, please, ask question, what i want, then make decision how to realize it. Not in different way. I suggest reasonable changes.
The problem is balance of snek invisibility range. IMO, set the effective level in comparsion to average big gunners perception (6?).. Snipers are not (usualy) in the first line. Make from sneakers ability to hit enemy bigguners, with 50 percent chance of unseen attack. It will be solid hit and run SMG PvP class.
