Nah Grom will be fine
Yes, totally from what we already know
Not sure, anything can happen, not big hopes
No, somehow things will be eventually fine canon wise
No, everything makes total sense
Nah Grom will be fine
In the original timeline, the first horde was controlled by Ner'zhul (manipulated by Kil'jaeden) then he was taken out of power, Gul'dan and the shadow council were the secret masterminds while Blackhand was the public leader (warchief), Orgrim was his right hand and only became leader at the end of the first war.
Thrall was born at the end of the second war IIRC, on alterac mountains. Grom in his late life was about 40-50, he's should be in his 20s here.
I wish jaina would die, all the problems in wow are her fault. She's always getting in the way of the solution to the problem.
Why do you think Garrosh is the way he is? It's not because he didn't have a daddy. It's because he's exactly like his daddy. The Hellscream family line is full of douchebaggery, Grom is no exception. Sure, he redeemed himself, but he could have easily just avoided the whole situation by not being a dirtbag.
