All you did is nerf items, and bring in more overpowered items.

I don't really consider any of the new items to be overpowered by themselves. Sure some are amazing like frozen gauntlet or twin shadows, but overall many of the new items have very interesting effects without being too strong. The only item that could maybe use a look is the new black cleaver, I'm not sure if it can be stacked to be made ultra-broken, but that is about the only item. Do you have more specific examples on how some items are op?
