Regarding the % of bloodpoint bonus...
correct me if i said something wrong, but did the devs told us that the bonus will be given to the side who need more players at the moment? if yes then i'm confused... me and a friend of mine saw something weird to say the least... little premise before explaining what was happened: we are in the same region. so, all it started when i enter on dbd... i saw that killer side has the bonus of bp so i did a match as killer... finished that match the bonus bp was still on killer. until now nothing weird, if wasn't for a thing: when i finished that game and quit from dbd my friend wanted to do a match as killer due to the incentive of more bp that was on killer... and surprise surprise, the bonus now was on survivor... at the start i was thinking of a temporary thing, so i logged in again to see if was on survivor... useless to say that i had the incentive on the killer, so my friend restarted dbd to see if he saw the same thing... bonus bp was on survivor while mine was still on killer. with that in mind, how is really working the bonus incentive? i don't believe that it will go on the side that needs more player in the moment at this point

It also depends on your MMR range.
I believe your MMR and region are taken into consideration when calculating bonus.
I have seen this first hand too, and it is definitely MMR related.
So, if your killer MMR is needed more than your survivor MMR, you will see a bonus on the killer side. If your friend's killer MMR is even more needed than that, they will see an even larger bonus.
