subclass ? HELP ?

Hello,
im newbie on this server and i would like to ask a few questions.

1) Can ROGUE win against pala/DK/lock/mage ? ----->> (i know he can, but is rogue overall weaker than the other classes?)
2) What subclass is in 3.3.5a the most useful for PvP ?
3) I´ve played on official server - BFA - assassin rogue and his DMG was amazing. Is it also on this server ? or SUB/COMB can out damage him ?

I think these questions are common and many people say that skill>class. But if 2 people have the same amount of skill but different classes, someone must be a winner bcs of luck/outplay/class. So i would like to hear some normal answers on my questions.

Thanks guys...
...CHEERS...

All of these answers could have been found on reddit or other forums. Anyway, rogue can win against all just need skills.
Subltety is most useful for pvp
BFA is nothing compared to woltk.

i am trying to play sub rogue. Almost everyone can out dmg me :D even tank can... my overal dmg in 1v1 is much lower than some tank warrior :D
And i didn´t mention mage/hunter/pala...their dmg is outstanding. I can´t even get them under half HP.
