There are a fair amount of changes involved when you make a videogame out of a Tabletop game. It is expected that you cant do the same in a roleplaying game with your friends and in a videogame, but in my case, I would like to have the same feeling when I playing a particular class ingame.
They already made an (IMHO) good work with the "Larian variant ranger", turning the videogame-challenged ranger features into a useful skill-monkey class with some interesting character concept options so I hope they could do something with the rogues too.
I understand without the existence of the languages ingame the "Thieve´s cant" is out of the table, but a rogue worth his salt would have another useful features that are not ingame.

Right now all characters have some of the key features of the rogues, namely, disengage and hide as a bonus action. Technically rogues do not lose the ability to do so because everybody can now, but I have to say that I find it fun ingame so I do not have a particular problem with any character be able to do that (I do not think that would work in a TT session but it´s fun in a videogame). But what I do not like that much is that now rogues´ 2nd lvl "cunning action" is only a free disengage. That would be a very watered-down version of one of the most useful signature actions of the rogues.
You want to make disengage and hide a bonus for everybody? Ok. But then you have to give something to the rogues that will make up for the loss of a distinctive feature of the class. - Second
Another of the key features of the rogue, the expertise feature that allows them (and bards later) to become "experts" in a particular skill, doubling the proficiency in two of them. I understand other features would be difficult to make ingame, but I cannot fathom what´s the problem with adding expertise to a rogue character. I hope that would be added in the final version of the game. - Third: Correct me if I´m wrong but I think now the "sneak attack" seems to be working differently. You only get to do it if you have advantage because you are hidden, attacking from behind, etc, but it does not seem to work if you attack a character engaged in melee with an ally (or merely near an ally like in pnp).
I have to add that the fact that you have to choose the skill as a button instead of being applied directly is not very comfortable to play.
I hope those things would be addressed later and we could enjoy one of the classic classes of any RPG fully in the game, if not as a full representation of the great rogue of 5e, at least a class that could compete with other classes in terms of usefulness.
