To prevent some drama I'd like to explain my decision.
The SWC Rules clearly say it is not allowed to shoot over a mountain, regardless the map situation. The player KQ broke this rule as you can see on this image:

Firing over "passable" smaller props such as medium walls, small buildings, and bridges. (It only takes a couple of seconds to walk around them) - Legal
As you can see this is only for smaller props, so no mountains. Though this might apply for a mountain's side edge.
In the NSL or on public servers the situation of KQ might have been evaluated in a different way, because it was easy for the enemies to sneak around that mountain's corner and kill him, but still he shot over a mountain which is agaist the rules in
THIS tournament. It is a thing players have naturalised, but it does not apply for the SWC.
Though this does not mean it is allowed to shot over mountains in general in the NSL/publics. They just handle it with another intention.
I might be that this should be written more clear in the rules, but that is not my task. I am just the executive.
It was never my intention to say that ballistic curve weapons should be used like coil or tempest, in a straight line. I just followed the rules that say "Dont shoot over a mountain!" There are several other points from where the cata could have shot without directly revealing itself.
In addition this is a teamgame, so your team should be able to defend you when you are a catapult, but that is another story.
I just gave the lowest punishment and noted it for myself as 1/2-infraction if something happens to him again, because of this naturalised ruling and I had a feeling that there would be a few "complaints".
Still, I am just enforcing the rules that were made before the tournament started and I am trying to keep everything as calm as possible.
I feel like I have missed something to say here, but I hope you are able to understand my point of view now.
