You have no idea what youre talking about.
A hybrid spec is not better in any situation than a pure spec.
No wonder you grey parse.
It’s working fine in SoD and Cata classic 
No one has given a reason it won’t work on the anniversary realms. And oh yeah it’s been live for a bit now and none of the fear mongering about it is coming true.
it dont matter. if it was the way you say it should be more people would complain about not having the freedom to change whenever they wanted or during a raid.
I disagree.
#1 I gave multiple reasons in my comment above. Please refer to comment 180, thank you.
#2 The realm isn’t long enough for impacts to be made yet on the fresh servers.
#3 Then you have no reason to defend it on the forums.
Well I’m sure you can provide some actual in game examples of a real problem.
I mean it has never happened before in all the time dual spec has existed. But maybe in vanilla there will be one, please give up an actual example.
