The old 'Mega PvP Guide' has stopped being updated and there are especially less builds for FOXES and RHINOS.
Heres the link:

Please Share your Lvl 50 + build in the comments. If u have a fox or rhino build put it for sure.

Make the format like this:
1. Class (and your name if u want )
2. Level
3. Base stats
4. Items you need to wear
5. Distribution of skill points
6. How to use skills against each class

There are a lot of builds in the old one but there are also a lot missing. It would be helpful if u posted builds for levels that are not there along with the levels that are already there.
