We do indeed have a tank that has a pull ability, but it's like you say, pulling in nearby enemies instead of targeting.. Magmatus, our fire realm tank has an ability called Eruption. It pulls enemies in while lava erupts from his body damaging and rooting them in place. This is especially effective when paired with his Lava Flow ability, which creates a bubbling lava pool on the ground, damaging, debuffing and burning (DOT) anyone standing in it. Just drop Lava Flow in the middle of a group of enemies, pop Eruption, and watch the carnage ensue. Salty is right too, though. There are a number of champions that will have a skill similar to what you're talking about, including one of the fan favorites from SXSW, Cinder. She has an ability called Ignition where she throws out her flaming tail and pulls a single enemy toward her. This is especially helpful in pulling enemies away from damaging your tower, pulling someone into AOE or Turret damage range, and more.
