So I was thinking about how they removed Dodge, Parry, Hit, and expertise from gear and reading a few posts from the doomsayers and honestly I don't think it will be that bad....
Personally I think it may be the start of something that Blizz has been experimenting with in Mists...multiple viable stat builds.
In case you didn't know Brewmaster Monks are kind of unique as they have 3 viable stat builds
Want an easier rotation? Focus on Haste!
Want to do more damage? Focus on Crit!
Want to survive against really big hits? Focus on Mastery!
This essentially makes 3 different styles of Tank and maybe they can do that with DPS?
Well Timmy I'm glad you asked that!But Mystery they removed reforging how are they going to do that if you can't reforge into different styles! There's not even gems or a lot of enchants anymore!
As such all though you will have gear that will change based on your spec (agi->int etc) the secondary stats should remain the same so multiple gear sets will probably be necessary for the people who seriously play 2 or more specs but not for the normal people
Gear should basically come in the following flavors
Haste/Crit, Haste/Mastery, Crit/Mastery, HUGE amounts of Crit, HUGE amounts of Mastery, or HUGE amounts of Haste
As such the new gear system will create the ability for people to try other specs easily and instead of having a full set of armor for a second set you may only have to replace a few pieces for the cutting edge heroic crowd but the casual crowd can easily just switch out the necessitys and heal normal and 5 mans just fine
But what about that Brewmaster System I was talking about?
Well what if we enter a world where because of this there are more viable choices for stats instead of a few small ones
Lets take the Mage for example the fire of which mainly focuses on crit...what if they made it so stacking haste created a new playstyle for the Fire mage that is still very viable lets say haste gives them a more busty option that eventually makes it so they can freely cast easy 1.5 second Pyroblasts instead of Fireball...bam new rotation however the crit build we all know and love is still there and can do pretty damned good DPS too.
..of course since this is Warcraft and these are numbers. As such theorycrafters will go in and find a definite RIGHT answer that will do more then the other styles but this allows people to experiment maybe in Mythic Raids certain styles may be better for certain fights and they have to switch accordingly but it gives stats are more meaningful impact and makes it so although there will always be a definitely best option ever there will be other right answers too and no real wrong
