Unpopular opinion, but I like the way the current star guardian missions / invasion are.
I don't care about the people who are used to have the missions as go-to gadget where you just need to play like you always do and pick up some sweet rewards. And it's kind of sad that people already complain about the difficulty, just because the haven't achieved all missions on the first day. For those who cry about being solo players. I randomly added people who played Invasion until we were 5. It's not that difficult to get 5 together. I can't describe how much I love being challenged by this mode. Figuring out strategies, who needs to interrupt certain monsters at what time, which monsters are to be killed first and what itembuild fits best is insanely fun. And there is no ks, feed, etc. I'd be disappointed if riot lowered the difficulty.
