Hextech was a good idea in that it made it so that there was a counter to things like 3 item Voli or Draven. But I think its too strong right now. 8 seconds where items are made useless? Items are what dictate the games and especially on things like GA. Having entire carries with no items while the enemy team does seems broken. Early game maybe not so much, but in late game it seems to be the sole factor in winning or losing. I've had rounds where they end after 4 seconds because my tanks had no items and my carries couldn't do anything.
