Decided to share my thoughts, how to increase rogues survival in PVP.
1st
Increase Vanish duration in PVP by at least 2 sec (1.5 sec atm, was 3 sec).
Also would be great if it will avoid all direct spells and attack like Shadowmeld does.
2nd
Make Restless Blades passive effect also available in all three specs with changes.
Restless Blade (for Assasination and Subtlety specs, with changes)
Finishing moves reduce the remaining cooldown of two Rogue skills by 0.5 sec per combo point spent.
Affected skills: Evasion and Vanish (for Assasination and Subtlety).
3rd
New spell: Preparation
Preparation
Cooldown: 5 min
After use for 120 sec (buff) reduce cooldown of next Vanish and Evasion by 30 sec.
Gives 2 buffs, for next 2 spells.
