Improved Gouge is a Rogue talent located in the 3rd tier of the Combat Tree. This talent increases the duration of the rogue ability [Gouge] and reduces its energy cost.
Functionality[]
If you don't use Gouge very often (which you may not, especially if you solo through PvE content with swords), then the utility of this talent may not be apparent. The main use for it revolves around waiting for cooldowns such as Kidney Shot and energy pooling. Some argue you can re-stealth by getting out of combat before Gouge wears off, but in practice combat always lasts longer than Improved Gouge and it is only possible to restealth if the enemy doesn't attack you for about a second. You can run out of range with this talent and re-stealth, though.
This makes Improved Gouge an invaluable part of PvP stunlock builds, as well.
