I'm a new player, so sorry if this is an issue that's well known to the player base (though I couldn't find anything mentioning it).

Generally the game runs quite smoothly for me, but sometimes my ping spikes really hard (6000+ for both sending and receiving) yet even with such high numbers the only way it manifests is through abilities. When this happens I can find dodging abilities to be impossible, as I'll still get hit when I've been outside of the indicator for a good couple seconds before it goes off. It also causes issues with casting, where I can stop moving and start a cast, only for the cast to be canceled a second or two later because the game seems to think I'm still moving.

Is this something other payers normally experience?

Are there any known fixes for this issue?
