yup on the gunslinger.....i'm also one of those who just assume that it will be added and the handgun issue will be settled.
with the scrake vs. new specimen: i think the game could use a new specimen. it's just like when they added the Husk and it drastically changed gameplay. i'd rather see them spend more time developing another specimen with animations, textures, modeling etc... instead of wasting time reworking weapon/perk/bonus code when they don't need too.
again for weapon restrictions......like you said CandleJack in regards to the Scrake resistance........it would make things much easier to implement. instead of having to modify and add new code for weapons, specimen, perk system etc... just remove the ability for other perks to buy the weapons and that solves all those problems that were mentioned. instead of buffing this or nerfing that, adding sway/recoil or removing it, adding/reducing ammo, removing stun ability etc... you can simply solve those problems by making the game so that you don't have to worry about the "ifs" like:
- what if the zerker was using a crossbow?
- what if the medic was using an EBR?
- what if the commando was using a katana?
by simply not letting perks use non-perk weapons, you prevent those situations from happening, which means that you don't have to do any additional tweeking to any other game mechanics which would actually require MORE time to do.
now for the body/headshot damage, see how weapon restriction works with that? you wouldn't have to worry about the SS being able to have rediculous headshot damage with say, a SCAR because the SS couldn't use the weapon in the first place. the SS perk should have the headshot multiplyer, for the perk weapons that is and the normal body damage isn't needed at all. i still believe a bow for a level6 SS should be allowed to get oneshot kills even on suicidal against any specimen.....again, they have to be headshots. that rewards the headshot multiplyer that the perk rightly deserves. if lowering overall damage affects the damage for headshots aside from the multiplyer, then just boost up the multiplyer to still allow for oneshots with the bow. again, that headshot mutliplyer wouldn't work on any other weapons besides the perks' weapons if weapons were restricted to perks.
if the SS could carry a bow and a LAR then he's got two weapons to use his perk bonuses. remember he's also got the 9mm. seeing as every perk is forced to have a knife and 9mm, it'd only be fair for perk bonuses to apply to those weapons. so the SS would still get the headshot bonus on the 9mm despite not being able to level with it, he'd have plenty of weapons to do his job.
all together, these few "simple" suggestions solves many of the issues that have been brought up in this thread and many other ones simliar to it.
