I think, there're more important things they're focusing their resources right now. And why do you need LO adv launcher if it will do all the same that the current one does. Advanced Launcher doesn't change some special things to make the game stable. I can achieve a same performance with default settings from ingame options as with Adv launcher, the reason why ppl are using it is because it's more accurate, you can adjust specific options as you want instead of using ingame presets
