It's because you're thinking as "a team", what i can understand of course.
But for a single developper, as I am, which not means a non-professional project, Construct 2 is very good to my opinion, for a 2D game.
It's really open, and you can easaly do all the "classics" you can encounter in a 2d game.
I'm more a designer than a programmer, and i'm on my own, and even if i can deal with some code, i'm not at all able to write one from A to Z, and that's not what i want to do.
For people like me , C2 is a very good solution, and will definitvely be when the webgl will be supported on mobile devices.
After all, it's also a question of "philosohy" : i tried GameSalad, Strencyl, GameMaker, and others, but the only one that talks to me is C2, and I think it's because it's just in the same "logic" as a software that i use everyday for my work as a designer : photoshop. (simple work on layers, for example)
Otherwise, I would have turn to a "real" developp program such as Corona. But in this style of software, easy to program, C2 is the best one i found, for me.
I love C2, I know its limits, and more than everything, i know the limits of the devices i'm developping for (mobiles).
When the dynamic memory usage will be supported, with for exemple CocoonJs (before the end of the month it seems, or with Ejecta), C2 will be a very very good option to develop for mobiles, and so other platforms, to my opinion.
C2 is growing up every month, as the HTML5 games, and I think it will be very intersting now, and in the future.
It's a kind of bet, the same as the team of C2 did.
I bet on it too.
