From everything they said and especially what Mike said here regarding the Warpath overhaul, I would assume they are far more changes than the ones they teasered on the news post.
Here is the post i am refering to:
There was another member of the community doing alot of assumption based on the very little things they showed, but Mike said there are alot more changes.
I am fairly certain this will be the case for the Necromancer Changes too.
I would just say that giving feedback based on what you are assuming is changing doesn’t have much merit, since they did those changes based on feedback in the first place.
I would wait until the changes drop and then discuss them.
