Rakan
The mechanic
Rakan's whole kit revolves around his allies: his E dashes to an allied champion within 700 units, which is both his engage and his only way out, and his Q only heals early if an ally walks into it. With Xayah on the team the dash reaches 1000 units and the two can recall together.
Why it needs saying
A support who can neither escape nor heal without the ally's cooperation. Without the call, the adc walks away right when Rakan needs them to get out, and waits for a heal they could have triggered themselves.

what you type
stay in range im dashing to you
in full english
Stay in range, I'm dashing to you.
the context
"dashing to you": Rakan does not move to a place, but to an ally. His way out after an engage is that dash, 700 units at most. An ally who walks away leaves him in the middle of the enemy team with no way back.

what you type
come to me for heal
in full english
Walk into my Q for the heal.
the context
Rakan's feather only heals after three seconds, or as soon as an ally steps into it. So the heal comes when the ally decides: an adc who ignores it waits three seconds too long, usually the three that matter.

what you type
rakan go i follow
in full english
Rakan, go, I'll follow.
the context
Rakan engages with his W, then comes back to an ally with his E. "i follow" promises him both: that the fight will happen, and that he will have someone to come back to.

what you type
kill rakan when he jumps in
in full english
Kill Rakan when he jumps in.
the context
Rakan engages with his W and gets out with his E onto an ally within 700 units. If he jumps far from his team, he has no way back: that is the moment to focus him, he is fragile.
