I know you said you think this build is bit slow. Let me spell out some things to you...This will get addictive and gets much more impressive a bit later, Ill just show you the rotation.
Target 1, VEX, Target 2, VEX, Target 3, VEX, Target 4, VEX, Target 5, VEX
Now you have 5 mobs coming to you! no need to be scared, you already are getting healed from the vex, in fact 5 mobs vexed = alot of heals over time, and you could always throw your Healing spray on yourself as well.
At this point you are prob getting close to needing to revexing your mobs, BUT, this is when the real damage come out!
Cast Soul Drain! This will do massive damage to the whole group, and later on you will augment this spell Fanticism.
Now lets assume you have yet to down your 5 mobs, 2 options depending on health.. recast Vex on all 5 or cast the Bound Fate from the Cabilist Spells, and or Shadow's Touch. Both of these are two other AOE spells that you have avalible at level 22.
This build give you the chance to solo a mob to redo your mana through the use of the spell Harsh Disicpline.
Level 31 build when this build really turns intoa monster!
