To be specific ...
Question: Could we get an exact definition as to what kind of UI mods would be against the EULA now. We assume if it doesn't interact with the datastream or alter the actual client's code, it would be allowed.
Answer: UI mods should not be able to violate the EULA. However, if through some bug in our system you should find a way to alter the code of the game such that it allows you to exploit or cheat then it will be considered a violation. However, while I can't say this will never happen, I can say that is it very unlikely because we have set thing up in such a way that it should not be possible.
