Trusted is all about the Operators and Administrators, playing classic can help but it's not a necessity to get the rank.
You need to continue playing and chatting and having a good time. I can't tell you when you will be made trusted, nor can I promise you will be as it isn't about me and I can't read the other staff members minds. =P
The only difference is water buckets, which I can do for you as well as any other Mod, Op or Admin.
If this is because you want to apply for Mod, all I can say is you just have to be patient.
