I've read about mixed feeling players were having about the stat changes on armor in WoD, however with queues being as long as they are I think it would be a really good change as players whom usually dps, they can now queue as tanks without rehearing, it will give a boost to those players whom play dos classes that are intimidated by tanking a chance to try the role without having to re-gear.
sure it can bring a lot of bad tanks into the mix, but that learning curve is there already.
I for one would love to go from lets say a feral druid to a guardian just by swapping a spec,
same thing for monks, dos, and warriors… all of a sudden there are way more tanks out there and queue times are shorter.
I don't even think a gem/enchant swap is necessary.
what do you think?
