When the population was high, you could see such trolling only late at night, when player amount decreased below 20 or so. I remember that a lot of special characters played almost solely in that comfortable niche. It was oddly enjoyable at times, if you neednt sleep that day of course.
When the population began to decrease, the trolling moved closer to primetime and then became regular, disrupting the usual flow of the game. When it is the norm it stops being cool to a lot of people.
I personally stopped playing regularly because of the population number itself: cRPG was enjoyable when it was a living battlefield, where you could have epic rounds fighting people left, right and center. If you managed superbly, you could kill 10 or more in one round! Today 10 is the total number of the opposing team
With OKAM, as long as servers are densely populated, "unusual" gameplay will remain an isolated minority and everything will be like at cRPG golden age. No need to worry.
