TFT suggestion
Since TFT is very RNG based: you can literaly gain useless items and very few while one guy has Infinity Edge on his adc, other guy has Rageblade and core to next item on his carry, what do I have? some items I can't equip cause I haven't recieved carry in shop and shop gives every single kind but buying everything and selling what I don't need doesn't help either
This means: items are very very strong thing in there
And you put some Hextech stuff that has both strong characters and ability that has AOE item denial? denies items and it's AOE so it's not 1 not 2 but all characters in a 9 unit hexagon
And you may have comp that just can't work little seperated cause the defenses would open to carries or some other reason
How about if the hextech passive was just little bit toned down? I can see that others have big impact aswell however the Hextech just activates itself at start and you added so many hextech champions that it's literaly easy to build it: at least one or 2 people in TFT have Jayce sitting in there or Camille
Just my opinion about the thing.
