So, while revewing I came across a question from '12.
This Question was closed for being 'not a real question'.
It's difficult to tell what is being asked here.
It's really not that difficult, LoL is a game played on a 2D map which is designed to look 3D. Due to that, there is no height parameter, and different mobility abilities (jumps, teleports and dashes) are done visually differently, but in practice they are just a 'faster move' on a 2D axis. Since different walls have different thicknesses, some abilities can cross some walls but not others. Some dashes can't even cross walls. So, it's not difficult to tell what's being asked.
This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.
It's not ambiguous. It's quite clear actually. It's also not Incomplete, it targets the audience that knows about LoL mechanics and as such the explanation I just gave isn't even necessary if you're able to answer the question (remember .SE is a community for enthusiasts to receive answers from experts).
If anything being 'not a question' is the last thing that that question is. If anything the question is Off-Topic due to being a list type answer due to the fact that League has around 140 playable characters, with at least a third of those being able to use an ability that can be in the scope of this question.
Even if this is 4 years too late, it's still bulldung. If you don't understand a question, because you don't understand the topic, don't mess with it, because this kind of stuff can fly under the radar for... well, in this case, 4 years.
While that question in particular should be closed, it's closed for the wrong reasons. It's a shame since that gives Arqade a bad image and is in general a lazy thing to do.
In the future, please do try to be more careful with your closures
