Assassin Help

[Devenge]

How does one play a assassin effectively? I feel like i'm doing a decent amount of damage but at the same time I feel like i'm not doing enough. Any tips? Any tips on the skill tree? Whats good and whats not good?

The most used DPS combo for Sin players is RMB + F in stealth. Because of that, it's best to have your Heart Stab and Dark Strike skill fully maxed. You can either take the Lightning Route or Dark Route (Lightning Route is the right most tree in Dark Strike maxed, along with Lightning Rod right most tree maxed too) (Dark Route is the left most tree in Dark Strike maxed). I personally prefer Dark Route.
