How do YOU play Taric?
I bring HP seals and focus the Q in lane. No one expects a meaningful heal when they try to attack my Ezreal.
Also, no one expects Ezreal to have NO FUCKING SYNERGY with Taric. Their relationship is at home. What they do on the rift with other people is separate.
But if you do pick Ezreal when your support picks Taric, please remember you have to become aggressive. Use that E to line up Dazzle-- don't save it to run away.
