My feeling is a mix between the answers. I like more than I dislike about it.
I don't know what situations allow people to duck out of sets with no penalty, but if a person leaves early for any reason they should lose points, I should gain points and I should get the win. This is going to burn people who have an honest reason for a disconnect, but that's the risk of gaming on a shitty connection.
I wish the kombat points were currency and not XP-style. I wish I could just spend the points on stuff I want that's available during the season. Alternatively, it would be cool if I got rewards that were specific to the character I was playing KL with. It would incentivize me to play a lot more and try out characters I don't feel as confident about. I realize this is a lot more dev time to come up with gear or a skin for every character, but I'd personally rather the season last longer to offset the time spent to create the rewards.
In all though, I'm pretty happy with it as a v1.0.
