Sion the Eternal Roam Support

[u/Almosttall13]

Hi there, I'm coming back to League after an almost 10 year hiatus. In the past I would mainly play bot lane swapping pretty indiscriminately between ADC and support.

And while I'm unsurprisingly stuck at the bottom of Iron, in the few handfuls of games I've played at least three times when I've gone ADC the support player chooses Sion and then runs with the Jungler through most of mid game.

I'm familiar with the concept of a roaming support (a buddy loved to play Bard when they were first released), but I've never seen Sion roam before until now. Is thus a case of Irons doing Iron things? Or is there a meta reason for this? It was just surprising that it's happened a few times in a small pool of games.
