Uhm.. Might be true for some software, though i haven't experienced that?. But they are often much more stable and usable, C2 has so many issues, so its more realistic to fix those first.
Why would anyone pay for a new editor, when games and apps run like crap on mobiles and are missing so many features, even on PC there are huge issues involved.
As of right now, C2 is useless. Why spend years on optimization and waiting for bug fixes, when you can get something more stable, and even free out there
C3 will be awesome, if they listen to their customers. But i doubt they will..
