The Assassin Role Is Problematic.
When you really think about it. It is next to impossible to get right.
You'll either end up with them being Assassins which means they go in and insta-kill their target. This is problematic because it is not fun at all for the victim and community in general and these Champions end up being hated and/or perma-banned.
Or you'll, as per this rework, tune them down in order to add "counterplay" in which case they end up not feeling like Assassins at all which disappoints their loyal fans/players, but the community as a whole are happier because they aren't as frustrating to play against anymore.
So yeah, there's no way to actually make them live up to the namesake of their role without any issues.
