Sweet irony coming from a Warrior....
Melee vs ranged isn't so much an issue in PvP. The issue has been casters that have to actually cast functioning against melee like Warriors given 500000 ways to sit on a target and prevent casting and was given to them to combat the casters like Frost Mages who would just jump around spamming instants.
CC in general is being trimmed in WoD. Now if instant casts come down some and casters have to actually cast, then melee won't need a hundred and one ways to interrupt you.
Everyone is being nerfed but it's po world of Warcraft for healthy game design.
Main concern is how this will impact Hunters where, if given restrictions, will require significant gameplay changes to our signature shot system and resource.
