Not sure if this was mentioned before or not, but a lot of the tooltips are pretty misleading. One that has really been bugging me for a while is raging strikes...

Raging Strikes says it increases your damage by 20%. Great, so does that mean it works with both melee and casters? Let's test it out! When you use it, the actual buff icon tells you attack power is increased. Going to your menu reveals that attack power "affects amount of damage dealt by physical attacks." So, does Raging Strikes work with casters? Probably not, right? I mean, the icon says only attack power (physical attacks). Buuuuut... it's been tested (and anyone can plainly see if you watch the numbers) that Raging Strikes works with all types of damage... not just melee, and yet the buff says melee specifically. If you cast magic dots with Raging Strikes on, you CANNOT overwrite the spell until it has worn off (thus proving empirically that a raging strikes dot is more powerful than a normal one).
