Suggestion: Give Karthus' wall the same "cast outside of range" feature as his Q has

When Karthus uses his Q (while inside his passive) and casts it outside of range, it automatically is casted on max range. Sadly, not the same thing happens with his wall. As a high elo Karthus main, I can tell it is sometimes frustrating when you are hitting that W button so many times and nothing is happening, simply because your cursor is a little bit too far away. This is pretty weird, especially since the way the Q is basically wanting players (or at least supporting them) to just cast the spells outside of your normal range.

Would be a nice quality of life change to add this "cast outside of max range" feature which his Q already has to his W spell too.
