Backstab was changed to sneak attack in 3.0. Rogues are still the only class with sneak attack in BG3. Backstab in BG3 has nothing to do with 2nd ed backstabbing. It's not an equivalent kind of ability. There's no reason to say no class but rogues should get Backstab advantage just because Thieves had a completely different ability I 2nd ed that was called backstab. That's just... it doesn't even enter into the computation. It's irrelevant.
The thing is there's nothing special about a rogue in this game because of how busted flanking is atm where everyone just bunny hops to each other back's like froggers. Which is why melee feels also stupid. Stuff like that is what is trivializing classes in general. Just having a reskinned and slightly different version of the same class and calling it other class doesn't cut it up for me.
Rogues have sneak attack. Nobody else has sneak attack.
