Blitz Mechanic Bug?

It feels like there is a mechanic in the game to randomly alter stats. I've noticed over the last several games (around 4400 that's all I have recorded) my attack damage, armor and magic resist seem to be meaningless random values on my screen. Where I can attack champions who only have 100 armor and no matter how many items I have they are like indestructible gods. Armor and Magic resist seem to work the opposite for me where they have 0 effect on the enemy. So you most likely have a mechanic in the game to give hidden stats to worse players but if "not" you may want to look into a bug causing values to not calculate as they are shown on screen. Also look into a bug that causes 100% crit to not crit every auto attack.
