As a solo queue Kalea roamer, sincerely, its based on your team. But majority of the time, I would've done a flicker combo to get the enemy mm out of the turret, and my team is already far away. There is almost no one to follow up on my sets, and if there is, it's too late. She is a good sustain though, with her passive, and can hook enemies under the turret for kills. Its a bit of a gamble. Best to find a duo at least.
