*resurrects thread*
I have to say I don't mind Kaka - in fact it is a very interesting map for both hunters and hiders. Hunters because if you've fond a prop that refuses to stay still you can have good fun chasing it around the rooftops as there are enough health/ammo packs to keep you going.
For the hiders, once you start running it is incredibly fun as anyone who has ever spectated me probably knows - you can duck and weave around the hedges and houses and can easily lose a tailer if you are clever in thinking about where the tail predicts you are going and change your path accordingly - psychology ftw! Probably one of the most fun times of running i have had is when sloth and a myriad of pyros were chasing me around the same couple of buildings but never getting close enough because they always took the wrong path allowing me to slip away
There are a couple of maps which I think are slightly obsolete in that no-one likes to play them but that would be off topic for this thread.
Finally, due to the change in rotation timings etc I don't think you can say there is an overplayed map anymore because there is enough time in between visits to make the maps still seem 'different' to the more recently played ones.
