Worst thing about the support items being overpowered is
You cant control what your support is building.
If you have a morg buiding full ap and they have a lulu building redemption and locket we pretty much auto lose the game because you cant win team fights against those 2 items if your team doesnt have any.
The only counterplay to locket and redemption is your support also building it, because there is no other item in the game that gives your team extra up to 4k~ health in a single active, both together give like 6~7k.
