The most sensible option would be choice and variety in Ranked. When I first heard about Kombat League, I was glad that we would have something different. Then it turned out that you can't play regular Ranked in season. That's stupid IMO. Why limit the player on every korner?
My main problem with KL that it feels forced onto the player. When it's KL season, don't you dare play anything else but KL. Come back regularly or we take your points! How insane is that?! If you don't have the drive and passion to play MK11 on a daily basis, they threaten you to hinder your progress with this stupidity. And what about having a life? If you have friends, a significant other, work stuff or a holiday opportunity and you happen to not be able to play for 4 days, you're already losing progress. These things just put me off and kill my desire to play.
What I would prefer personally is choice. NRS should let us play 2/3 Ranked, 3/5 Ranked and Kombat League simoultaneously. You can toggle a lot of things, so an option for 3/5 Ranked instead of 2/3 wouldn't be so hard to implement I guess. This way everyone could play according to their own preference. If you want to breeze through sets you could keep 2/3 but if you want to take your time and adapt you could choose 3/5. Kombat League should stay 2/3 beacause it's a long road for the most of us but I wouldn't mind if it's 3/5 from Demi God because it's basically the Top 8 of KL.
Options, choices, please!
