Minor spoiler: Blade of the Ruined King and Wicked Hatchet are actually Season 3 items.
During development, we actually had a very powerful version of Madred's called Tankbusta that completely destroyed the Bruiser meta (yes, it can be done!). However, we found that there was a lot of crossover between Tankbusta and the S3 items, so we scrapped Tankbusta and brought over the S3 items instead.
BotRK is definitely weaker than Tankbusta, but we'll separate them out again and give TT its own replacement if necessary. Also note that this was the plan when we were launching TT. I don't know if they're still going to be on SR as-is, if they're going to get changes, or if they're scrapped from the map altogether.
