This will not promote WvW if its going to allow this mount to be used in PvE
Here is why...
if PvE players avoid pvp content for years why would they stick around now that we have a mount?!
if they suck at pvp this new mount will not make them play better and they will still die regardless forcing them to respawn at their home checkpoint
After the first few weeks when people will get their new cat mount they will leave for good...
If that's an attempt to promote WvW i'm sorry but its a terrible one
We should've given the Alliance update instead allowing us to join other guildies and help each other out and also open some people eyes into a new content.
