For rogue power scale difference between teamup and none is too wide, And she has one of the worst thematic to Actual mechanic failure in game (You Shouldn't use ability you copy), almost comparable to Blade. Yet , She's almost never talked about and is overshadowed by Gambit, DD, Deadpool etc.

Rogue is one of the most interesting Brawler tank in the game in my opinion. She feels athletic, snappy and fast kinda like spider,bp,dd etc. She's also visually and thematically one of the BEST Looking character in game.

But she was released in arguably one of the WORST patch in the game's history, in a Balanced state with a high Skill ceiling ,in one of the least popular role. On top of that Characters Like DD, Gambit and Invis etc. Warped the game around themselves to such a high degree that she quickly became overlooked and rarely discussed.

Which is why her design issues are rarely talked about. She has arguably worst block mechanic in game, she has a max energy of 100 and drains 60/s so she can hold her block for just about a second and half while blade has 120 energy, on Top of generating Dash Charges , Gaining Unstoppable And Having Higher Damage reduction. This is not even talking about DD who also has stronger overall kit. The intention behind her block is you can punch back with more damage but her Punch in practice is a gap closer/all purpose mobility tool.

Also, The biggest design theme to mechanic failure, her ability absorption. There is a Higher cooldown if you Use ability than if you were to never use it on top of having higher cooldown based on which ability you use, For instance Wolverine ability has a Massive 40s CD if you use it while a Weaker ability like Hulk's Clap has a 20s CD. However if you were to absorb. but just don't use anything it has a 15s CD.

So in practice it is better to just use it on a DPS, And then press your entire rotation with added damage instead of Making Clever use of stolen abilities or Trying to find a character that has an ability that could turn the tide in your favor.

This is not to say she needs massive buffs or even rework to her entire kit, But a bit of polish to her would go A LONG way. Having a Static cooldown for her absorb which is a reasonable cooldown ESPECIALLY For when you miss or having longer window to use/get benefitted for using copied abilities is how it ought to be.3

Lastly (obviously wishful thinking) , I would Love it if she had her entire "Block punch" mechanic reworked in favor of having just a regular 40 damage gap close punch but her right click is a Shield similar to Strange or mag's which will add to the ever so needed and most requested "Shield tank" in the game on top of giving her something to defend herself with in such a poke heavy game.
