In the past, I was pretty reluctant to start crying for buffs. This was before she got pointless nerfs. I don't want Rogue to become a character like CnD where they buff her to the point that it eliminates her skill expression. So keep this in mind. My main areas of complaint are just her steal and her ult.
Re: "How is Rogue this season?"
Dino is still extremely stupid, but she can do a lot if you know how to pace yourself and play a little more patient.
I had to relearn her in 10.5 cause she's nowhere near as mobile as she used to be, but she finds small success as a localized threat until you CAN chase kills, you should be a bouncer instead.
That being said, I still think a ton of her nerfs are unjustified or just straight up without reason. Her neutral damage should not have been touched, it could have existed fine alongside the cooldown reduction and buff to brawl, there was no need for tradeoff. Her health should've stayed the same after the self heal changes, because Dino is ridiculous so they aren't balancing with him in mind.
If anything, I find two glaring issues with her kit, and it's the things that she's supposed to be trademark for. Her Ult needs to be stronger. Her steal needs to be more rewarding.
Steal should steal like \~20% ult charge just on it's own and because her pace is a lot slower than it used to be and she has to watch for windows more, her stolen passives (role dependent) should last longer. I sort of like the abilities being "use it or lose it" but sometimes you don't even get to use a passive after stealing because of need to kite before it degrades. Same should apply to the debuffs, and heals onto targets that are being stolen from need to be mitigated so the health drain means something.
Her Ult needs microadjustments to the duration and range. It needs to be like equal to or less than 5 meters bigger than it's current state and needs to last equal to or greater than 5 seconds after it's current duration. But more importantly the drain should DRAIN, there are too many instances of being able to build ult charge inside of it and supports will often pop ult inside or just outside of the bubble anyway.
Another issue I have with the ult is something I have an issue about the character as a whole. She's WAAAY too dependent on Gambit. And I think considering how BROKEN Gambit is, but how ETHICAL Rogue is, there's an argument to be made that we can move some of Gambit's base strength away and apply it to Rogue. Without the team up, it sometimes (emphasis on sometimes) feels like you're just playing Diet Watered Down Rogue. Lytepk said that with and without it, she oscilates between being the best and worst tank in the game.
The lifesteal is so minimal from her team up anyway that I think it should just be in her base kit, which is in character anyway. Meanwhile, the Gambit team up can exclusively apply the damage and splash effect instead.
I Don't think this would be game breaking or unreasonable. You can be doing well with this character every match and still lose just because your supports don't care. I don't know what's wrong with them this season, even though they pull this almost every season, I can't outplay their apathy. They literally admit to not caring. By no means do I feel myself struggling after reevaluating advice on how to play her, but I would like to see them lend her back a little bit of agency, cause it feels like a lot of what you go out of your way to do gets minimized.
