Worldtracker does absolutely no good for weekend events and makes them worse.
With such a tool clans spend more time doing nothing and sitting in strip or lobby and seeing who makes the first move.
From a pking perspective whoever makes the first move will be perpetually disadvantaged because of the public broadcast, and clean fights are not possible with the current state of the clanning community (looking at all of you).
Worldtracker removes the need to scout efficiently/plant leaks because now you will have roughly enough information to tell what you're dealing with in a world.
TL;DR, it does more harm than good
