Help W/ Channeling Build

I've been having a ton of fun in FA and AB's recently using the following channeling build, however there are some issues I was wondering if someone could help me improve. Here's the build:

Grasping was Kuorong {E}
Channeling Strike
Spirit Rift
Destruction
Swap
Rupture Soul
Dash
Res/ Ancestor's Rage

I cast GwK, use dash to get in range, swap with destruction and use rupture soul. I'm also quite able to stay out of melee range with spirit rift and channeling strike. Escape from melee attack when unprepared is also easy with dash and swap.
The set backs (sans the obvious of being in melee range with a caster) is actually getting into melee range reasonably. Dash simply does not cut it, and people are wary when a caster rushes towards them.
The second major issue is targeting. I have to be targeting Destruction to effectively pull of the swap, and this frequently involves missing. Would draw spirit be more effective? or is there another way to transfer spirits more effectively?
Any other suggestions would be much appreciated.

Swap is probably your best option since it will pull you back out of combat. Draw Spirit's benefit is that you can cast it without targetting the spirit itself, and it will simply bring the closest spirit to you. This could lead to problems, though, if you get the wrong spirit to come to you. Rupture Soul / Grasping will still go off correctly, but you won't get that added Oomph from Destruction.

[skill]Dark Escape[/skill] may be another viable alternative to Dash, since you won't be attacking while you run in to position. You'll need to put attribute points into Shadow Arts, but it'll give you enough time to get in where you want to, while making you take half-damage.
