The “corner = facing” point is the specific reason the RC had to bring in the explicit ruling about individuals being “protected” from being charged in a facing that is flush against another unit.
Yes, they had to write it explicitly, because under the normal rule it would not actually protect the Individual
It’s not so much that the corner is both sides (in reality it’s neither side but a meeting point of two sides as per geometry, mathematics and the English language) but because your leader point is in the side that is the side you are charging. With a pivot you can make contact with that side. The posts in the pics are mostly just shortcutting that you can do that.
The whole character thing and corners is something that needs revising so that it makes sense (something other than the bunk that a corner is two sides) to allow characters to be charged by fliers in the characters front arc where there is no room to fit - instead of creating a room for cascading bad interpretations with flawed assertions.
There’s only a handful of rules needing ‘fixing’ in what is otherwise an amazing ruleset.
The post from Matt James specify that no pivot is needed. if you are in contact with the corner when your leader point is in the flank and you declare a new charge, it’s a legal charge. meeting point of two sides = kind of in contact with both sides, I guess.
yeah it’s the idea that corners are a side that is the problem - players shouldn’t need to string together a couple of rules and use bad geometry - an explicit rule would be better for all in the long run.
