Cool, I was waiting for some criticism lol. And I do really mean that genuinely.
Tracer: I'll address each of your points.
1. Lack of professional reviews - I doubt there's actually a professional reviewer in RMS; 99% of the reviews is written by an average person who doesn't get paid (real money) to do so. Naturally, that person will have a bias. Any review in RMS has some sort of bias, I can guarantee you that much.
2. Love at first sight only happens at movies. - I don't know about you, but if within even the first hour I don't like the server, I'm not gonna "stay for the good part" anyway.

3. Might contradict with RMS reviews. - Even within the RMS reviews there's a TON of contradiction. Some players say its the best thing ever, some say its the worst. What matters then is -why- they say it, which I intend to put a lot of in every review I do.
4. I agree with yC. - I'm not going to put the RMS name on the reviews unless yC himself wants it. Until that time, any review I or a team does is just as valid as the next one.
5. First impressions causes a type of cancer that is called assumption. - Sadly, assumption makes the player decide whether he/she wants to do something or not. Keep in mind that the attention span of people is generally short. If you lose that attention, they assume it's not good and move on. Cancer or not, its something server owners have to face.
6. Bribery. - As much as I would want money doing this, no one in their right mind would pay us to make a good review for the server. They can't pay us in ingame items since we dont intend to stay in that server, which only leaves real cash. I doubt server owners pay anonymous people real cash for reviews. If there is such a person, that person is wasting money. Plain and simple.
7. No one in their right mind would jump servers just to review it. - Thank you for calling me crazy lol. As of this post, I have 5 people interested. Call me loony then. :p
8. No successful attempt at first impressions has ever been acknowledged - That's because they try to pass off first impressions as something concrete or something final. They draw months worth of conclusions from 5 minutes of gameplay. That's not what my idea is about. What I want to do is pass first impressions as just that, first impressions. Like Tom~ said, this only gives the initial thoughts on the server. It's possible that it's not actually what the server is about. What's important is the first impression is what ANY new player will go by upon entering the server, whether accurate or not.
9. The server might change. - I'm well aware of this. That's why I don't look at reviews that are over 3 months old lol. If a server gets a "needs improvement" review, I'd gladly revisit their server in a month to check if they've improved or not.
10. Server owners/players mob RMS whenever there's a bad review on the server. - That already happens my friend. Thankfully we have banhammers and stfu pills to solve that, care of our loving mods and admins.

RMS always contains some bad review; I'd be more concerned if it didn't.
11. No server owner in their right mind will list on RMS if this is implemented. - I don't intend my review to be any more or less valid than the next. If RMS wouldn't want such a review on the site, they'll tell me and I'll stop posting it. That simple.
Now, Pandora.
Thanks. I'd be more concerned if you thought it was absolutely perfect lol; I know I'm not that smart.
I've already been thinking about the concept of a team review of a server so that we get not only multiple times but also multiple perspectives. What's stopping me from saying yes outright to this is that it may be overly cumbersome for a simple first impressions review. We'll probably see if this is needed after the initial test run of the idea.
As far as score goes, I'd rather not rate this by scores but by a simple "recommended to try" or "needs improvement". Like I said, first impressions are not necessarily the "real scoop" or deal on any server, so putting a score on that server with just a few days of play seems unfair. BUT, the actual first impressions review would still be necessary, since that "real scoop" is being overshadowed by what tracer calls "cancer called assumption", which ultimately might prevent new players from trying out what otherwise might be a great server.

Thanks for the criticism guys. I really do like thinking about this more thoroughly.
