There are more ways to counter strip. But your stat explanation is not one of them.
It is true strip does not ignore builds. However on a server like this one ALL classes are very gear dependent, Just reducing the chance to be stripped with your build does not take away the fact that once you're stripped you're doomed. And with out current stalker gears it's not that hard for them to get way higher dex and still have huge reductions/ have enough time to strip you.
Rune pretty much explained it already
The things you stated by comparing those classes(& strip) are highly lowrate oriented and several of the comparisons made do not match our server. Dex based characters do not have lower attack than the swordsman class, they are equal if not even higher.
Dex based characters don't have balanced attack with the merchant class, dex based characters have way higher damage/attack than the merchant class while it should be the other way around.
Bottom line (for me, just my opinion) : Yes, altering your build by increasing your dex can reduce the chance of getting stripped. But you can in no way really call it a 'counter' to strip.
Making fcp bottles drop-able would completely ruin their current economy. And personally I see no reason at all for this change. Stalkers at this moment have gotten the gears to utilize at other things than just strip. And they don't need a boost in any single way. So no, I definitely do not arrive at your conclusion o.O;
