It is a shame that the EA UFC games have soured most people on parries because of their free counter and freeze.
Parries can be implemented in a decent way. UD3 already proved this with their clinch parries which resulted in over/under or single collar all without the free counter and freeze.
EA UFC has shown it can do better with their live service. The opportunity to incorporate both types of parries is present- boxing & karate (deflection & catch) - as minor and major parries respectively.
Boxing parry- deflection
Karate parry- catch
They can start by splitting the retreating evasion into pawing (mobile and tied to grappling) and backwards sprint (adding lateral sprint too).
You can then have parries inputted through the grappling input (L2+RS). Flick for minor parry and hold for major parry.
Minor parry will deflect the strike and you can counter over it but it will be blockable. Major parry will be an improved grappling entry to whichever direction you transition to (single collar, over/under, single leg, double leg etc) which will function like a kick catch from where you can counter or transition- both deniable.
Holding the major parry input would result in:
Up: Lead arm extension (pawing/stiff arm/post etc), active block of rear hand; +L1: rear stiff arm, active block of lead hand.
Down: Lead pawing, active block or lead hand; +L1: rear pawing, active block of rear hand.
Left: Pull in; +L1: Heavy pull.
Right: Push; +L1: Heavy push.
Holding any of these inputs and getting within clinch range will initiate the clinch from that direction.
For example holding L2+R UP and getting within clinch range will get you into single collar unless denied. Holding L1+L2+R UP will result in double collar tie etc.
Doing this to someone holding block should peel through block (deniable).
With this we can reintroduce parries as they were meant to be. Since the upcoming patch is primarily grappling based, this is extremely relevant as parrying is a crucial underappreciated aspect of grappling as well.
Without the free counter and freeze the parries should work more realistically and with all that was learned from head movement. Parrying can return as another tool which has it's own pros and cons instead of how it and head movement was earlier- a lot of pros little con.
