Maybe this is just me but I've been seeing a handful of my friends and people I know finally using WAR/playing it slightly more due to this change. If this was the road map the dev team was going for then they have accomplished that and I don't think they will change it back, even if it means dissatisfying us who love the cone (and I hope they do revert it back).
I do agree that it just isn't fair for us who do take the time to learn how to position with the cone (Hall of Novice teaches this!) and basically telling us to readjust instead of the other people learning it so they listened to the latter.
I used to be excited about tanking an Expert but now when I tank it I'm just like "let's get it over with". Furthermore, it's either I play another role and miss tanking or I tank and feel sour about it.
