They’re still working on PVE tuning pretty heavily.
I don’t think they’ve even glanced at PVP tuning outside of the hastily cobbled together dampening changes to counteract the 40% hp buffs.
There’s no shot anyone can guess what the best PVP class is going to be because it could all change tomorrow depending on how they decide to tune things.
Locks/Mages/Rogues/Warriors are generally safe choices, but honestly who knows at this point.
Its DH by a mile.
Man I hate this YouTube trend with the dumb exoressions
Solo=DH, 1v3=DH, large scale=Warlock.
Dh, rogue, evoker, hunter
tbh playing what you enjoy leads to unhappyiness and suicide unless you like demon hunters but other then that good luck
play what you like but if you roll arms let me know when you about to queue 
And markers
At least Venruki has a mustache, not a fan of supatease Amish beard.
I don’t know what I enjoy as I havent played retail in years.
I like melee I guess more than anything. Something that doesn’t have 87 keybinds.
Ret at A 
Yea he’s only biased towards mages and not rets.
Currently the most broken and easy to play? Demon Hunter
Consistently broken and strong with 3 dps specs to choose from if one is underperforming? Rogue
Both pretty safe picks tbh.
You need a PhD to play Outlaw so mmmm really only 2 to choose from for most people
Ret is easily S tier, even if the damage profile is still burst oriented.
Sub rogue is more challenging to play then Outlaw 
So really the only option is Assass then for most 
Honestly, I can’t stand that face they make. Legit lookin’ like an over-excited Orangutan in a zoo. 
Not as good as the last 2 seasons but enjoyable.
Who doesn’t love poorly made tier list from biased rank 1s.
It’s such a weird way to try and generate clicks on youtube when they’d be far better off releasing actually good content.
Let’s see you try and do better!
