No, it's not. They already switched from c to cpp at least with extensions, and very small primitive constructions. *Athena code is a big mess of many very bad, very complex, very hard to understand, trace, and read the code. So the process of switching to use CPP features will take years (like I said more than 1 year ago). rAthena needs more powerful developers and contributors (just my vision) for finishing a lot of things much faster. They physically do their best with the code, but this is to be clear is not enough... A lot of problems as I see comes from supporting legacy things and current user-base. If they will drop user-base support (community / administrators) on the same day will be created a new emulator where users will not be dropped and rAthena will die in months. So, as you see, this is very hard and responsible work, and current devs to be clear, working really hard.
