No! Classes u mentioned are already made in previous expansions.
We need content that would fit into Warcraft lore in classic time (raids dungeons).
New races for example ogres.
new items in classic style normal looking with little bit of epic spice nothing exagerated like in BFA.
We need cool new class in Warcraft classic time like for example ShadowHunter as Voljin was.
IN classic + there has to be old raids with normal and heroic difficulty.
thats about it.
