Healers Are Basically Tanks
What a lot of people don't seem to understand, when playing league, is that healers are basically tanks.
Sure, they're not tanks in of themselves, but when they heal someone else, they are giving them more health, which makes it so that it takes longer to kill them, making them harder to kill. So when you are targeting whoever they're healing, you are basically targeting a tank. The tank of a healing spree.
Take Soroka for example. With runes, masteries, and at max level, her heal can literally cooldown in almost 1 second. 200 heals plus 60% of her AP. You do the math. How much can she heal in a second? Would you like to test you DPS against whatever she can heal? Now imagine targeting an actual tank, like Garen, with 80% damage resistance, while Soraka is providing heal to them. Good luck killing this Garen now.
In a team fight, this is the roles you should actually target first, from first to last.
- Healers
- DPS
- Tanks
A lot of people actually does just the opposite though. First they go for the tanks, then they go for the DPS, and at last they go the healers.
