How to make leveling more interesting

[fadetree]

I've always thought a diminishing return of exp for killing the same mob in the same zone would be interesting. The system would keep track, and everytime you kill a particular mob in a particular zone, then exp would be slightly degraded according to some curve. Eventually, you would get next to no experience. This would be in addition to level-based exp reductions.

This even makes sense, sort of, since 'experience' is supposed to mimic you 'learning' from encounters, which is why its called 'experience'. How much new are you going to learn from whacking a mob for the 1000th time? I mean, I killed crags for FIVE levels on my shaman. If, after the first 100 or so, the exp dropped off, I would have had to relocate. Say, to mammoths, which I am now killing by the truckload.

This sort of happens anyway, in terms of levelling out of the range of a zones mobs, but it would be interesting to apply it on a per mob basis and make it happen a little faster.
