Calling/Specs

This is the Rogue build I'm planning on running 5x initially:

For single target DPS I will use a rotation between Piercing Shot, Quick Shot and Barbed Shot. AE DPS will be run by Trick Shot. Healing will be handled with Cadence. The pet will tank in PvE for non-instances and will DPS in PvP. For a finisher I'll use Rapid Fire Shot to increase autoshot speed and then use Concussive Blast until I need to Rapid Fire Shot again. I set up a complicated key in ISBoxer to handle those pesky melee people--It has 6 steps:

1. Slots 1 and 2 get Repelling Shot and Static Shot respectively (ie, one AE knockback and one root).
2. Slots 2 and 1 get Repelling Shot and Static Shot respectively.
3. Slots 3 and 4 get Repelling Shot and Static Shot respectively.
4. Slots 4 and 3 get Repelling Shot and Static Shot respectively.
5. Slot 5 gets Repelling Shot.
6. Slot 5 gets Static Shot.

Now, each step has a Do Not Advance for 1.5 seconds clause and also during each step whichever characters are NOT getting Repelling Shot/Static Shot are doing single target DPS. You can basically spam the key until you see the melee who's on you rocketed away and rooted. Then it just cycles through knockback/root in sets of two characters.

The pros of this calling/spec is that you've got insane ranged single target and AE dps. You've also got solid survivability and many different ways of handling melee that get on top of you--None of the other callings/specs I've seen handle melee swarms very well at all. If single melee do get on you you can also easily Cadence them to death which also does lots of group healing.

Thoughts?
