• Zed
  • E energy cost decreased.
    • As a system, energy is intended to give champions spikes of power that fall off with extended
      combat times. Given the current state of the game and more extended fights, champions that
      use energy as a resource have found it more difficult to find success before their energy
      depletes (note: this section is repeated for energy users in this patch). In Zed’s case, we’re
      lowering the energy cost on his E and giving his shadow a little freedom so it doesn’t always
      need to walk beside him.
  • W – Living Shadow
    • Shadow Spell Mimic Range :: 2000 >> No Limit
  • E – Shadow Slash
    • Energy Cost :: 50 >>> 40

Competitive Systems

Having a premade duo is a slight advantage, and while current Apex Tier (Masters, Grandmaster, and Challenger) players aren’t able to duo with anyone, the system only works off current rank. With this change, we’re tightening up the Apex Tier restriction to apply to MMR as well.

The goal of this is to prevent climbing smurfs from being able to duo queue into Apex Tier. That said, decayed Apex Tier players and the highest skilled Diamond I players may also be impacted by this change.

Up until now these players could duo and reliably get into Apex Tier games, which isn’t fair when the people they’re playing against can’t duo. If this change works as expected, we’ll evaluate shipping it to the rest of the world with plans to re-evaluate before Season Start.

We first rolled out this change back in patch 12.10 on the NA and KR servers as a trial and the results have been positive, so we’re rolling it out to the rest of the world. From now on, players with an MMR of Masters or above will no longer be able to duo queue in Ranked Solo/Duo.
