Well, he is already excited for the classes so what you do is being negative for no reason, also you don't answer any of his questions so that's why people are annoyed. It's normal you are getting replies like that. Personally I like this pruned version better, I joined in the end of wotlk and never got a char to max level until cata but even while I was levelling I already had many spells on my bar that I don't even use. I just had to spam 1 or 2 skills to deal max damage I could and I didn't like that.

Bloodronin4life to me demo and destro looks way more interesting than affliction in bfa, they have cool animations and spells with better rotation. I am levelling a warlock too currently, destro melts everything... chaos bolt is a one-shot and your pet handles mobs while you prepare another chaos bolt haha it's actually faster than some melees
I think you should pick the race that looks cool to you, don't mind racials. You can pick the best dps race but when they add Zandalari that may change, don't risk it if you don't like spending money on race change. My pick was Nightborn!
