This post is somewhat a summarization of imbalances in cumulative rank
It seems that many people would want to see their cumulative ranking and be a part of it! This is an example of how a cumulative rank would look like on a userpage, I didn't make it as outstanding as the singular gamemode tabs as I read that most people see this as an 'interesting' or 'fun' rank to see, not as a needed feature. So there's no reason to make this a big thing/tab.
Here I made a list containing statistics about the rest of the userpage
Performance: Big problem as Edgar_Figaro mentioned, needs alot of discussion and balancing, I myself don't have enough knowledge to go into this too deep
Performance graph: Has no problem as far as I see. It just shows the summed up ranks you gain and lose every day
Ranked score: Scoring is way different in every gamemode.
Hit accuracy: Taking the average acc of all gamemodes wouldn't work, as it's easier to SS in CtB than in other gamemodes. Also OD <-> PP curve relation plays a role/problem in this considering taiko/mania/std acc differences
Play Count: I see no problem in adding up all playcounts in each gamemode
Play time: I see no problem in adding up all amounts of hours played in each gamemode
Total score: Scoring is different in each gamemode
Current level: Leveling is different in each gamemode
Total hits/fruitscatched: Mania has way more hit objects than std for example. Also problems with CtB etc.
Maximum combo: No huge problem but this would be imbalanced (consider converts, and non-converts on maps)
Kudosu: I see no problem in adding this up. I think a mod on each gamemode takes about equal effort - nvm I don't know I have no experience in modding
Replays watched by other: "there are less ctb players than std players so you'll have less replays watched on that" . ok yeh that's true I guess
Ranks: It's easier to get an S on mania and ctb as you can still miss and get an S rank. It's easier to SS on CtB. Some imbalances
To be honest I myself don't really care about some of the small imbalances as most people see this as an 'interesting' or 'fun' rank to see, I just wanted to point this out because.. idk
