You were never in the thread to begin with.
This may not be the right comparison, but in games like TF2 for achievements, there are servers out there to exploit getting them. Yes I know it's no where close to being the same as Leveling, BUT the same thing that I'm about to say DOES apply.
Whether there are leveling exploitable maps or not, the people will choose which ones to go to. Many Gamers DO tend to level legitimately, granted that the leveling scale is not so difficult. I don't know if some of you have noticed, but the medic perk from 5 to 6 is like growing up from 12 years old to 30 in one year. Now I'm not complaining about it. I'm just saying some people won't like the grind, so they resort to either doing a thing like "Siren Tag Team Healing" or go to Friendly Fire Servers. That could technically be called an exploit too, and even if you don't use those particular things, there is always getting attacked by a clot on beginner whilst your friend heals you. =/
Another thing that bothered me is that you said "KF is meant to be challenging". Now I'll give you the benefit of the doubt and say you meant something along the lines of "It's not a game where you just walk through suicidal with a knife alone and kill everything instantly" That being said, various games can be meant to be played in one way, and be taken in a whole other direction. It makes me recall one story of Smash Bros being a gag game with nothing serious behind it, yet it's one of the most popular nintendo games out there.
I'm just saying that the white list isn't doing many people good, especially the map designers. I know many mappers who have very intricate levels that can be played without anyone finding obvious exploits, just to have a fun time and level at the same time, but people find exploits (Some times they can't be avoided for the sake of the amazing map), and it will get the good old toss into the scrap bin, never having seen the light of day on KF. It takes away the mentality of "Oh I'm just playing West London to farm, I don't really want to be on this lvl cuz I've seen it a million times"
That is just my view on things and I want to hear other opinions and defend what I stand for in a rational way without resorting to (Like many have) using swear words and caps lock.
