when they made the rift herald changes, did they completely forget what morde ult does?
because im pretty sure they have not a god damn clue how stupid both a drag + rift herald + zzrot running down a lane is going to be. not. a. single. clue.
depending on how snowballed your team were beforehand, you are just going to outright win the game.
and ask him to hold onto the herald item until morde can get drag with his passive. once he gets it then you just spawn herald mid along with drag and there is not much the enemy can do to fight all of that.
for example, both are very common midlaners that also have alot of wave clear.
