Guild Wars 2

the quickness and vengeful hammer skills are some of the most energy intensive thing on rev. Only way you are gonna change your energy usage with those two legends is to save IO for burst, and VH for aoe/healing or alternatively don’t use skills.

When it comes to shiro if your using the quickness buff you shouldn’t be using any other skills while it’s active. I prettt much only used to finish bursting an enemy down, or during champions and bosses I really only used if my energy hit 100%

the shiro quickness costs 10 energy a second (net -5 regen), and the hammers cost 7 energy a second (net -2 regen). having either of those on means your energy is already depleting, and if you go spamming skills its obvious you will run out of energy (especially since you only start at 50)

if you are using an upkeep skill you need to use other skills very sparingly

If you avoid opening flight with up keep skills, you will notice the energy bar slowly filling up. When it is almost full, it is the time to use skills with high energy cost or up keep skills. After practicing for awhile, you will get the rhythm of your rotation.

Autoattack and swap legends off cooldown.
