I think you mean dp/sonic...
Dual/sonic has two things going for it: the -damage, but also the -res from /sonic. Lethal damage is mostly your damage with pistols, and is highly resisted. /Sonic lowers resistance, making this less an issue.
It will need redraw, but that's not huge.
Sonic/ has a nice other side going for it...the stacking -res is excelent with scourge. If it takes you a couple attacks to get a scourge, those attacks just layered a good ammount of -res on the target....which means you'll hit HARD with your scourge.
Neither is a bad pick. Pistols have more AoE, and your big bubble should make its tier 9 a LOT safer. Sonic has good mitigation in its stun, sleep, and knockback. It's a matter of taste to you, then.
So I'm torn between DP/Sonic and Sonic/Sonic. I pretty much have it down to this:
DP/Sonic:
+Chemical ammo -dmg is made more effective by sonic resonance's -res.
+Chemical ammo -dmg would "stack" with sonic's +res shields
+Much more AoE than sonic attack.
+Crashless nuke so toggles won't drop (albeit, I don't know much about Hail of Bullets)
Sonic/Sonic:
+Tons of -res to stack with sonic resonance's -res
+Siren's Song rocks socks.
+Aim
Is there anything I'm missing here and does anyone have any insight into either of the builds? I would roll both but I only have one character slot left on my home server.
Thanks, all.
