People invest time and money sometimes in a toon and a nerf is frustrating.
Pvp is not the only game mode, an NERF can disrupt utility in AAT for example.
For me the way the DEVs have solved this has been very appropriate: to launch a toon (not a leader) that balances the pvp a little.Let's see the examples:
Old Ben - B2 and Zam
Zmaul - R2d2
This is a very simple solution that does not displease the vast majority.
No one feels like buying a Ferrari and shortly after forced to put a speed reducer.
