What would make the most sense would be Seasonal Statistics to go along with the Seasonal Leaderboards so you can see peoples wins and losses for the season, or peoples PKs for the season or BKs or gralats. Would help a lot

Well we can already see, at the very least, 50 people's PKs, BKs, and Wins durig a season via leaderboards. You can see more by filtering.

I don't really understand what you mean by this

To also see the amount of deaths that you got this season from baddys/player killing.

Yea. tek I'm saying your statistics on your profile should look like this
Kills: 30,000
Deaths:50,000
Season Kills: 2,000
Seasonal Deaths: 500
Baddy Kills: 5,000
Season BKs: 30
Spars: 23,000-14,000
Seasonal Spars: 500-100
Would give a more accurate look at how active every player is in certain things at the time.
You can see he is doing much better in spars and PKs as of recently compared to how "he" used to do.
(of course you can switch off deaths)

I think a death statistic would make player profiles look weird especially for players with high amounts of PK's because the death stat for them would be high and trying to fit a 6 digit death number beside a 6 digit PK number would be hard to properly fit and just look really weird.

Not to mention, there is a huge difference in losing a spar and being killed, spar is a one-on-one activity so the only thing attributing to the loss counter is a constant variable(as in, there is only ONE way to lose).

There are numerous ways someone can die, baddies, spar losses/ties, etc. Most notably would be when someone solo PK's a tower and ends up in 5vs1 situation, given all these factors there is no way that the number of deaths can ever accurately represent a PK'ers ability to PK. There may be ways to change it so things like baddy deaths don't count towards the statistic but that would just be a waste of time to implement.

So you're saying the people that win tournaments aren't necessarily the best? Next thing, we'll just eliminate those because they don't represent true skill.
