The main thing is people come here to learn about pServers, so they stumble upon Caalis files then they don't need anything else. But if they have 2 perfectly good sources to choose from they could at least attempt to help them. Any kid that has enough time in his day to play Flyff for hours on end can Google some kind of C++ or C# tutorial sites with no problem and learn a little bit of coding with no time at all. Hell, you can even go to pixel2life and get C#/C++ tutorials.

Rhisis as is, works.
Not perfectly, but it works enough. (And the source is being released sometime today, which will only further it's development)
I'm not so sure about osAFlyff, but I know it's been making progress.
And to be a bit blunt, if people want to continue to cry about Caalis files, then they can go to another forum. Simple. Plenty of other forums welcome Caalis files. And most allow Rev_3, so that's just even better for all the people that rely on bugged and dangerous files.
Also, as been stated before... This is a DEVELOPMENT forum, you can't Dev Caalis files. Sure you can change some thing in the database like NPCs and items... but not much more other than graphics.
Then you have the people that use it for getting packets, well... all those people that need it for that have it. So they don't really need to worry at all.
