why not buff the underused classes since PVP is not the only thing that there is in game there is also PVE and nerfing classes will just ruin this balance.
and just to be clear there are alwase FAVORIT and BETTER no MMO is truly balanced in both usefulness and coolness between all classes.
In the suggestion there are not only nerfs but also buffs. You cannot only buff some classes to make a balance, you have to nerf things that are broken.
And in those mmo where there is no PvP balance, the roles are identified. Some better for PvP and other better for PvE. Here the roles are not identified and you have SK useful for both and DW just for PvE, the people will end choosing SK because it is more practical. The same with turtles/crane etc.
