Invincibility on backdashes wouldn't work with the dash mechanics. Dashblocking while being invincible? Loooooool.I also consider the meter system very good. Adding invincibility to back dash would make some justice to defenders. And not to forget the dial strings. They have uses and are awesome.
Also, about 2 meters vs 1, having 1 meter completely trivializes certain aspects, such as X-Rays and MB cancels. 2 would allow you to spread out options between two bars and lessen that trivialization, as well as give you even more room to expand upon options. Like, read some of the ideas I had in my post.
We'll take how this impacts Sonya, for example. With some of those additions in mind, you could give her alterations such as EX cartwheel being projectile invincible only, and making it unsafe. She would lose the ability to safely blow through everything in the sun, but, with the roman cancel, she can spend an extra bar to not only make it safe, but usable for starting pressure or bailing her out on a bad read. You see where I'm getting?
Wigy pointless moves will always exist in fighting games. It's not something that you will always be capable of avoiding.
