They will be nerf every other class....at least the ones who need to l2p...

You're right. Sam Jackson was both physically and mentally strong in that movie. So will sorcs in db.

I thought the changes make them close to balanced with other classes. A guildy confirmed this when he said he was probably not going to play his sorc once DB comes in, when I asked why he laughed and said "I won't be overpowered anymore and don't really fancy being at the same level as everyone else" most honest answer I've seen regarding these changes.
He's now looking for the next overpowered class, think at the moment he's looking at stamina nightblade
