You bring up a very valid line of questioning. As a Warrior I am interested, because like you stated we may or may not have a parry advantage.

As for the tier argument yes it has been closed, by the "assume every point increases comment". BUT this is a terrible stance for a dev to have. BY HOW MUCH, is a very important thing.

I do hope someone answers your question as to block rate and parry rates. It would be very valuable information to the community. And as far as the community goes we should all be seeking answers to how much these stats increase our %'s so that we can weigh how much each stat is actually worth.

Again "Players can assume simply that as the stats that affect this grow larger, the effect will become greater." is useful information. BUT I still want to know how much it increases. I am not going to simply settle for oh just put stats in whatever and I am good, and neither should the community.
