But that is not the point is it?
The rule being violated is no pixelwalking. Simple as. There is a place near mid doors where you can jump on the wall and see short over the mid smoke. Once again, not too OP but still a clear case of rule breaking.
One of the casters said that in an old CS tournament, one team managed to lob nades through a glitch in the skybox and it was very effective.
This boost is semi effective because if you know he is there, you can 'easily' pre-aim waaaay before the guy manages to make the jump. Look how quick this guy gets there.
It was only effective because LDLC was taken by surprise. Yes, it is a
****** boost, but so are all the other pixel walking boosts. LDLC had a similar boost, not as effective, but still containing pixel walking and broken textures. it is just a badly optimized map, I won't deny that, but I don't fully blame Fnatic.
EDIT: I never said it is not against the rules. What I simply said is that it is equal to any other type of pixel walking in terms of rules. If you use a calculator during your maths exam (when you are not allowed to) or you copy your friend, you still cheated either way, although one is more effective than the other.
