I have read many C2 docs over the years and they were in general at an amateur level. My suggestion is that if you are charging "big boy" per annum prices, that you hire a trained tech writer
I wrote the manual. I also wrote all of C2. Are you suggesting we get someone who didn't write the code, and doesn't know the inner workings, to write the manual instead? That hardly seems like a way to improve the quality of the manual.
Also if you want to build APKs, you can always sign up to PhoneGap Build - the paid plan is also a subscription, and costs more than Construct 3, which provides a full game development IDE and a build system, at a cheaper price.
Still, if you don't want to use Construct, you don't have to. If you think a different tool will better suit your needs you are welcome to go and use that instead.
Anyways this thread is already too close to a totally unnecessary flamewar, so closing.
