Riot hasn't done this in awhile. Morde is still on the PBE and riot is announcing another for release. This isn't a bad thing, I could get used to something like that, it's just a little unexpected. While I'm guessing this is because they finished working on the two champs relatively close to one another, the meta is going to be kinda shook up for awhile, especially if both are high on the ban list and other champs like yasuo or akali start coming through more often because of it. Two lanes are going to be slightly disrupted now, but in a good way.
