Unplayable Due to Lag/Packet Loss

[akumasilent]

I've only recently received an invite, and upon playing some bot games, I was met with such severe lag and rubber banding issues that the game is almost unplayable. Everything aside from me freezes for several seconds, and these freezes occur every 10 seconds or so, even when I'm just on a zipline, clearing neutrals, or rotating. It was like this from start to finish for both games I've played so far.

I haven't had issues like this in any other game, and the game runs fine in sandbox. Is this just a networking issue and I have to wait it out? Or is there something I can do?
