I really don't understand the sentiment. I could see if, for some reason, you actually liked this system and didn't want it to change, but the forums are for feedback and many people dislike the system. SE doesn't seem at all receptive to these complaints, but voicing concern is the primary way of telling them that we'd like some kind of change. Saying it's pointless and to just deal with it would just result in SE being even less likely to make any change. Also, the situation would be even worse if everyone ran around tagging one mob and leaving a FATE. Every FATE would just time out eventually and you'd get credit, but it would bottleneck new FATEs from appearing.
