Yeah i am the salty one here
I'm not disputing the usefulln ess of Grappling hook. But its not part of our dps rotation for pve. And an ability with a 20 sec cd that has most of it usability in the outdoor world isnt really worth considdering as to why you should definately play outlaw over enhancement.
Outlaw is by far the easiest rogue spec to play. If you know to roll for 2+ buffs i'd even call it as easy as BM.
There are definately different difficulties for specs.
I love rogue, why would i switch?
