Just because your support can heal you, doesn't mean you can be a lazy butthead (Mr. or Ms. adc). Everytime I play a support like Soraka or Nami, my adc gets lazy, and stands in one spot while farming while getting beat up by the enemy. Our heals can only do so much! Please don't take your advantage and turn it neutral because you won't try dodging skill-shots and so forth.
Edit: (Mr. or Ms. or Mrs. adc)* Gotta satisfy the people.
