i barely play reyna but its a mid ult tbf. i usually pop it for eco purposes. like if i have 2650 or something on last round of half i will ult and go guardian so i can heal without buying orbs. or when im out of orbs
Idk how to explain it but people wait for the right moment to ult/they wanna have an highlight moment whenever they pop it so in the end 'that' round never comes so
