Drop rate question

[destroika]

I'm not making any suggestions here, I just want to list my train of thought and see what you guys think...

A card's drop rate is by default 0.01% along with a few other rare gears, so on this server with a 3x drop, that means it has a 0.03% drop chance. I haven't used probability since Algebra II in HS so I'm a bit rusty, but I know that it would be around 3000 kills of that one type of monster to have a good chance of finding a card - if you've been on the only one on the map the entire time; most likely a very boring week. (Btw, does the mob spawn with pre-set drops, or does the % chance happen on the kill?).

On a private server with less than 500 people, the economy tends to hurt, and the odds of finding what you're looking for off a merchant are pretty slim. Personally, I like the lower leveling rate, but what if the drop rate was 30x? So the server would be like 5/5/30. This way, the extra drop rate would make up for the lack of people, it would only take about 300 kills to have that same drop chance. So if someone happens to find an mvp card, it's not for sale for 999mil zenny, it would be the normal range. And if you have an odd build you want to test out, the chances are that no one will be selling your items. But then you could just go get them yourself. And new people to the server can go find starting cards/gear much easier to take out the rough edge of starting an account.

But if it was this good, why aren't there any low rate servers that do this? There must be something wrong with it that I just don't see. I'm open to enlightenment.
