DP/Sonic - Can we make it viable?

[Darling]

I rolled up a DP/Sonic Corruptor, picking powers for flavor & not mechanics. I tend to do that, then figure out a viable mechanical build after. However, with DP/Sonic I'm a little stuck...

 

How is this supposed to go? I looked over the forum here, but didn't see another thread on it.

The running idea at the moment is: slot all the AoEs with +Rech & Damage Procs - drop Liquefy on the mob to hold them long enough to not take the alpha - Spring Attack (slotted as stated) into the mob - Hail of Bullets (slotted as stated) which also brings Melee defense to 45% softcap (with slotting for defense) - go wild with AoEs until the mob is finished - get out, hit the Boss with -Res from Sonic Siphon & Disruption Field on the Tank (or whoever) & help whittle him down from there. Repeat.

 

Is this a viable route? Better ideas?

 

Looking for inspiration!
