Large latency spikes when interacting with monsters in zones/maps

Hi there, I'm having an issue in regards to latency spikes when interacting with monsters in zones.

When I'm in maps or zones, oftentimes when I interact with a pack of monsters my latency will spike - the larger amount of monsters the larger the spike. I'll go from 30-60 ping running around, to 600-1500 ping after striking a pack, sometimes unable to control my character or being rubber-banded for close to 30 seconds in some scenarios when playing with a friend. There have been issues where I've died, my friend tells me I've died, and on my screen I've been able to run around for ~10 seconds until finally the game freezes for a second and I'm dead.

This is a new issue and I haven't encountered this in Leagues previously.
