I want to develop an Indie game (try an RPG i know this is hard), is there a commercial support for the engine, because i`m afraid that forum is not enough for me?

To be honest, if you study through the sample, tutorial,and source code (you can buy them through the website) I am pretty confident that you will be able to make the game (regardless of the genre), and if you are stuck, the good community will try to help you provided that you specify the actual problem. This way you don't need commercial support and you learn a lot more. If not then if it is specialize feature within the engine, you can do some arrangement with Esenthel Dev (with some fees of coz) and they might give you some additional feature that not listed. Hope this help
