When you have a charge of Relic's Shield, and you see a cannon minion

And then fed adc comes and crits it. http://33.media.tumblr.com/9c4004fe748f05dab79417e1776fe491/tumblr_inline_nm6l4krqf41rxys9h.gif

if i could upvote 30 times for the what about bob reference....i most certainly would![slayer-pantheon-thumbs]

But then Draven takes it

WHAT ABOUT BOB! BOB BOB BOB BOB BOB BOB BOB lol, GJ Laughing fish.

No. MINE!

and then your ADC does everything they can to take it from you. abilities, AA's, actively AA'ing it before it's in range for you to execute it and then using a spell to take it before you can react (or while you're in the middle of your AA animation for that matter), etc...

When ever I have a tank support with relics shield I always ping the cannon minion so they can execute it. Same with when I'm playing or ...I ping it like 4 times so they know to let me execute it >_>
