If your support takes heal is it better to take barrier?

I would imagine you yourself taking Would actually not be as bad as you think given it's benefits.

it has a shorter cooldown than heal and you can use it to escape someone or get the upper hand in battle.

But I guess if you're unsure, yes perhaps barrier..

Cooldowns can be a big factor in what summoner spells you take. or other things like Early game Kill potential.. grievous wounds..

I've seen some ADC and even supports take this bot lane and have it work..

#You just don't want double heal

It does happen, though but you can space it out effeciently to not get the penalty. ike say to them "You use heal first"

No. Barrier is only good for yourself. Good for Mid lane since they're squish squish. If he takes heal just take exhaust. The only summoner spell that I would consider getting for "yourself only" as an adc in your lane would be cleanse or ghost.

Exaust>Barrier

The damage reduction is incredibly valuable.
