Parry is broken.
Dexterity/evade is also broken.
Recovery time has been increased in all areas of combat so badly that the AI gets guaranteed hits on specials and heavies now.
And the AI has faster recovery time too.
Look how slow my Hypo is and I immediately evaded once he started his heavy.

^Increased timings is the norm now and started immediately after maintenance ~2 months ago. Immediately! It was so noticeable. Pre maintenance 2 months ago I could keep a combo going in LOL, after maintenance it's much harder. You can't play the same anymore. Everything hits now.
Our time needed to recover between:
evading then evading
blocking then evading
punching then evading
evading then countering
...is so huge that the AI gets free reign to do whatever it wants (specials, heavies, parries, follow up attacks). It's ridiculous.
More ridiculous recovery time. Since when does the AI ever recover when we block their medium attack and immediately counter? Never! They can't. It's not possible. Pre 12.0 or even several months ago this was a guaranteed hit.

I evaded his heavy with enough time to spare but our champs are so slow and the AI recovers faster. Ridiculous.

More nonsense. Recovery is so slow that the AI gets free attacks in and I can't do anything about it. We used to have a bigger window to do things now it's almost nothing and the AI is gluing heavy and special attacks to us.

Not to mention lag that never existed pre 12.0:

Forget the lag for a minute although I think every player should receive a permanent weekly compensation package filled with tons of potions and revives until these issues get fixed, but that's another issue.
It's clear that dexterity length and all the timings associated with combat are being changed and distorted. It's so obvious at this point, and I'm fed up! Games are played under the assumption that it's a clean and fair one but the blatant meddling with timings is so sickening and discouraging.
Hope we can get some answers regarding these issues.
