Hey, before things here get even more out of control, we, as in the whole ETF2L admin team, have been reading through all the feedback from this thread and have come to the conclusion that the wallbug rule is very vague and doesn't explain the intention as to why it was even mentioned on the list with other banned spots.
First of all, we published a list like this in order to be more transparent towards our players regarding what exactly is allowed or not allowed in matches, with the aim to have teams and players report us any new spots in maps that can be exploited. An example of a map where this is the case is Gullywash, where a player is able to shoot through the shutter on last when it's closed or taunt with Equalizer/Escape Plan from elbow to the balcony without dying from it.
The part that caused a lot of controversy was this: "All maps: Sticking to angled walls", which is understandable, as it doesn't give any explanation to what instances it is applied to. Before anything, this has not been allowed on ETF2L for years now, as Muuki already said in post #6 in this thread. Regardless, we will be removing this part from the rules for now and I'll clarify it properly here.
We have decided that it's not fair to prohibit players from using simple game mechanics that can be done without the use of scripts or without the use of 3rd party plugins. With this in mind, due to popular demand, we will allow people to use the game mechanics as they see it fit. However, the use of map only mechanics, such as sticking yourself to an invisible wall, for example on Product, from where you can gain information about what's happening in the map without being able to be damaged by enemies is not allowed.
Any similar map exploit that is reported to us will be discussed within the admin team and we'll try to come to a conclusion about them as quickly as possible.
ETF2L's intention was to make people aware which spots in certain maps are allowed to be used and which are not. The post we published applies to old map spots that players in the past have been warned not to use. The only difference now is that they're of public knowledge now, instead of players having to come to us in order to know if a certain spot is allowed or not.
