From what I understand the partnership between BLEED and DSG is not financial, i.e. Bleed doesn't support DSG financially in any way (other than the bootcamp that Bleed used when they were in ascensions, and gave to toast for DSG) so everything is from Toast's pockets and sponsors if they have any. This partnership is what riot calls an "Affiliate Partnership" and its similar to what academy teams are. What this means for DSG is that, in case of emergency situations with the players and the org not being able to find a possible substitute, the partner (who may have initially designated a player as a sub? I'm not sure) can lend the other org that player. Riot also mentioned that the partners can also work closer in content, but i don't think DSG is doing that.

First off I think that you are cherry picking results here, if we were to compare Asuna's and Zekken's ACS on kickoff it would be vastly different. But to keep it fair over the last 90 days ( around Week 3 Stage 1, so excluding kickoff and masters Madrid) , Zekken does have higher stats than Asuna in all of the fields. Now you also said that Asuna's best agent is KAYO, which is exactly why I don't think comparing them would be fair, they both have vastly different roles in their teams, Asuna playing flex and Zekken is the primary duelist, which would be Cryo for 100T.

So the way champs works is that each region has 4 spots, 3 from their respective region's playoffs and 1 spot for the team with the most champ points (excluding the ones which already qualified) in that region. What this for SEN is that, if LEV wins against KRU in the upcoming match, SEN will qualify off of points as SEN has more champ points than KRU.
