Demand a high critical hit chance with its skill set

Malice (5/5) - 5% increase in critical chance? Considering there is no class that attacks as fast as a rogue, this is a great talent. If you have 2 weapons that have a 1.5 FFXIV Gil second delayed (typical daggers) you are swinging 20 times in 8 seconds, at least 1 critical with 5% chance in that sequence. That is only counting auto attack. Fact is that the rogue demands a high critical hit chance with its skill set. This talent is great for such little investment.

Ruthlessness (3/5) - 60% chance of getting a free combo point after a finisher, sounds great, as combo points are really useful. In practice though, it is not all that often where 1 combo point makes the difference in a battle. It does make some battles go faster though and is a great place to spend talent points if you are working to go down this talent tree.

Murder (3/5) - 2% increase to overall damage on various target types. All player characters are considered humanoid. The undead type is the only major type not listed but pretty much anything you attack will be humanoid, giant, beast or dragonkin. This talent gets better as you get better. 2% increase gets very noticeable when you start doing 400dps.
