Block Breaking issues started yesterday

I’m having problems in game specifically in AQ and AW that started yesterday and are continuing today. If I’m holding block and the AI attacks me regardless if it’s a dash or a regular attack my champ is dropping their block and eating a combo. If I’m holding block and they attack and swipe to evade the champ stands there and eats a 5 hit combo. Please look into this it is very frustrating and my alliance is starting to think I lost my mind. The only thing I’ve changed recently is my masteries (removed dexterity).

This is not an issue of a missed parry or evade. This is happening on champs that I intentionally hold my block to, in an attempt to bait out a heavy, for example BPCW or Mordo. Sometimes they won't throw a heavy, but will attack with a combo. The combos are going straight through my block and I get hammered.
I still have dexterity in my masteries setup.

Still happening for the past week. All the above. Either attacks break my block , my champion wont dash back and is just standing there getting hit and Sometimes will move forward when I’m holding block
