PSA: @ALL RANKED PEOPLE: USE PICK INTENT
Nothing irritates me more then people who don't use pick intent. It's there to strategize, to use synergy. To work around comps. You're not forcing yourself to play said champion, you're just letting your team know who you're thinking on going. That way you don't end up with an accidental all AD comp or all AP comp. Or if 3 of you are planning on going teemo. It might not do anything, or it'll decide who wins or loses.
Use it, it takes one click. It helps the whole team plan.
