I think this is a necessity. I've heard most monsters you need to deal about 30% of the monster's hp to get credit if you didn't tag it (I've also heard enmity etc. but think hp for simplification). With those kind of numbers, if four or more people camp a spawn, kill the mark with about equivalent damage dealt, then only one of the four will get credit.

Even if the marks are much more forgiving than 30%, with enough people contributing, eventually, even if everyone contributes equally only the person that tagged it gets full credit. The system should support a vast number of people considering that everyone on a server is looking for the same mark on a given week (unless that changes). This is worsened further by the fact that rank B and A marks go down in under a minute, causing anyone that isn't camping it to have even less of a chance of getting credit.
