Since Tripwire have put an artificial bottleneck on the release of custom content through the whitelisting, they have a duty to update this whitelist as regularly as humanly possible.
And they've done it as much as humanly possible.
If they can't do this then the whitelisting should be removed. It is suffocating the modding community and the whole player base.
I think you're over dramatizing some people's complaints. I've been on plenty of 30 man servers, that by definition can never be whitelisted, and they are packed. I've never gone more than 4 rounds playing KF, ever, before the server starts to fill. I thought the white list was a poor idea from the start...simply because why regulate something like perks in a non-competitive environment? But TWI said they wanted players to take pride in their accomplishments and so we have the whitelist. That isn't going to change unless TWI does a 180 in their attitude about the sanctity of perks. Since I doubt that will ever happen....the whitelist isn't going anywhere until they can find a way to approve maps w/o Steam updates. It's sort of a "you can live with it or whine about the fact you have to live with it" situation.
As Fel said if the situation does not improve modders, players and admins will stop playing KF through frustration or boredom.
Some will, probably. But you're inflating your own reaction to seem like everyone's...and that's obviously not true. Perks are ephemeral things, they eventually cap. This isn't Battlefield 2 and people knew that going in. 100 hours is what they estimated it would take to rank all the perks up to 5.Anyone who plays KF and doesn't realize this are deluding themselves.
If you couldn't even play your map until it got whitelisted, that I would understand. That would be stifling. That would seem tyrannical. That would lead people to boredom, having no option but to play only approved maps.
But the crux of your complaint is that you're deprived of one element of the game,
for at worst a month or two that, eventually, doesn't matter anymore. What happens when you cap out? Are you just going to quit playing KF?
And again...TWI said they're doing the best that their circumstances allow, and that part of this is entirely out of their hands. What more do you want out of them that's realistic?
