The poll results show that about 25% of the people who have an opinion about parry believe that it is too effective.
If you were one of those people, can you share some insights about why you think it's too effective? If you can do it without revealing a bunch of IC information.
I think it's well balanced. I came to that conclusion after considering a few factors.
Effectiveness versus NPCs
Effectiveness versus PCs
Effectiveness versus various weapon types
Counters to parry / being able to work around it
The caveat here is that my character is on the low end of total UE. I do not have any reference for what it is like in some sort of min-maxed build focused on parrying.
