Balance Issues

Seems kind of shitty that Fizz and Ekko can just build Trinity Force and then build full tank and still do as much damage as a carry even after so many nerfs. What i think you guys can do is nerf the AS to 25% increase the AD by 5 on Trinity Force, i think this would be enough to make Fizz and Ekko build normally at Mid/Jg but not completely destroy duelists like Jax and Irelia or other champs like Hecarim or Ezreal. Thanks and maybe you guys have already found a solution! GG
