massive delays in game

alright so i was playing a game, and for a good 38 of the 40 minutes i had MASSIVE delays. not actual lag. because enemies still moved, i still walked and did damage, but my skills wouldn't animate, enemy skills wouldn't animate, and neither would auto attacks. so i'd be losing percentages of my health without anyone actually looking like they attacked me. they would be in the range to justify that attack, but i wouldn't see projectiles, skills, nor would i get notified that kills happened until MINUTES after the fact. i could still talk with my team and maintain communication with them too.

an example of it was when i was in a teamfight at mid. i could use my abilities, do damage, and would visibly see enemy healthbars dropping, but they would just stand stationary after being killed for about 2 minutes. then 2 minutes later suddenly im hit with a dragon buff, 5 announcements of deaths and the eventual ace announcement, and saw my back animation just start even though i was already in my shop. this didn't start occuring until the patch dropped TODAY.
