Based on the fun I have had with 5 druids.. im guessing it would be fun to do all rogues. Not much use for anything but open world stuff anf BGs ( you can get them the hive mind mount for getting around in BGs ). My druids are balance, but they can "prowl" and stalk the enemy and blow them up before they knew what hit them. I only PvP for the CTAs or if someone attacks me. I keep war mode on for the 25% extra rewards I get ( im on under-represented alliance side PvE realm ). With any other team, my 5 pals for example, I cant hide so i get ganged up on all the time. Its nice on the druids to be able to quest and use prowl to stay undetected so i can finish WQs and assaults faster.
