hence why I wanted to target this ability for those who doesn't grab blue buff. If you are a champion that always grab mana regen or blue bluff, then this spell is not ideal for you.

But if you're a champion like MF or Jayce or can't grab blue buff because someone else in your team has it, then clarity seems like a good idea to have.
