This post summarizes the problem perfectly. As you describe, things like "yuri shenaningans" and battle fortress absolutely kill casual play because there is no reason to do anything else--the gameplay is boring and redundant-- and lets face it, the units are gay af! You sit with bf, I sit with bf, you sit with bf, I sit with bf... you see where im going with this.
Interestingly, this is the exact thing that kills competitive play as well! You can not be creative or try new things or even be very aggressive or try anything skillful because really what u should be doing is teching ASAP to get those, as I personally would describe, "super gay" units that make everything else irrelevant. Which results in, I sit with mirage bf, you sit with MM mag, I sit with mirage bf, you sit with MM mag.
While this patch is very well thought out, theres no way to truly fix the problem by tweaking the numbers. Yuris units are just too.... unengagable. You would have to change their function altogether imo.
