When Irelia legend readies a unit by paying 1 power, does this count as choosing the unit for the purpose of Irelia's ability that gives +1/+1 when a unit is chosen?

Ruling: The Irelia legend ability does not target or choose a unit when you pay 1 power to ready it, so it does not trigger the +1/+1 bonus from Irelia's ability that triggers when a unit is chosen.
