Tank Leona Support
Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Why play Leona?
Against the current ADC Meta, having a tanky support is going to help win games. You need to keep their ADC off of yours at all costs, and Leona is one of the best supports to be able to do that. You can jump straight to the back lines with your E, stun them, and ult their entire team to slow them down, and take damage while your team cleans up their front, and back lines.
