Two things.
First I'll go over my general thoughts on parry as it is now.
Yes, at the moment it kind of sucks, however I feel this is somewhat by design. Many secondary stats got reworked and rebalanced for the new level cap and the new ilvls for gear. Because of this it seems that in a way it was like a soft reset for some of these like parry. Ignoring the removal of other stats affecting parry and making it a flat mitigation percent, the scaling for parry score to parry chance seems to have been rescaled to fit the projected parry scores that players will eventually have from the more powerful gear we will eventually get later in the 3.X series of updates. So now, at the beginning of the cycle, parry seems to be terrible because we suddenly need so much more to get a decent benefit to parry chance, but later down the road it may even out. This sort of rebalancing is not uncommon in MMO's for attributes that have percentage based effects because if it was a steady linear progression eventually our gear would be giving us so much parry that our parry chances would just keep increasing until we would always be parrying.
So, summation, parry kind of sucks now but it may even out and scale more to what we think we should be doing/getting once we get farther down the gear progression path for 3.X.
Secondly, Ceodore your are being quite self defeating with the way you present your ideas and arguments. You want people to see things your way and agree with you (whether you admit it or not), yet you do so by berating them, insulting them and generally exuding a "I'm better than everyone and you are all idiots" attitude. This tends to be quite off-putting to people and makes them not want to side or associate with you. They may even agree with the ideas you are presenting but will just disagree or dismiss you based on how you come off and make them feel. So if you want people to be more open to your ideas and be more willing to try to see things from your perspective, perhaps you should try utilizing more tact in your execution. Also if you want people to be willing to listen to you, you need to be willing to listen to them and not just try to shut them down.
