What you want has already been discussed throughout the ages of Construct 2. It's a called "Native Exporters". The talks about this Holy Grail, the Messiah, the one thing to bring balance to the force, and make Construct 2 the game engine of all game engines. The thing people believe to be the end all of performance problems and plugin problems via Construct 2.
Anyways.
Would it better? Yes of course Native Exportation would be better. Much better than the system that C2 has going for it right now, hell I'm pretty Ashley would agree that if he could snap his finger right now and Native Exporters existed with C2, he'd do it. This way, there wouldn't be anymore "WHY IS IT SO DAMN TEDIOUS TO EXPORT TO MOBILE?!?!?!!??!"
But it isn't that easy to create Native Exporters, and I'm barely even a technical person, but it's been around 1 year since I started to look into videogames and become familiar with programming stuff and the conclusion is that nothing is easy when it comes to programming something.
Creating Native Exporters is quite a big project, if Scirra had a team dedicated JUST to create and support Native Exporters, that'd be great.
