Guild Wars 2

Blood To Power
Deal 5% more damage while your health is above 90%.

This is currently an appropriate, if underpowered trait. It gives a little added punch when lifesteal isn’t doing you any good. It doesn’t really add anything gameplay changing or interest, however. I would suggest the below.

Blood To Power
While above 90% health life siphoning deals 100% more damage and nearby allies are healed for 20% of what you would siphon.

This does two things in particular. It allows skills that are useless in situations you aren’t being attacked to be worth using- Such as Life Siphon, boosting the damage level above dagger autoattack. The passive boost to Vampiric damage is just a little added boost to make up for the 5% lost on the old trait. The ally healing throws a little bit of passive support into the mix. You may not be getting hit, but you’re helping whoever is.

Feel free to consider the numbers flexible. The idea is what I’m looking to propose here. Feedback is welcome!
