One of my favourite toons I have ever played in both PvP and PvE is my ice/kinetics. Ice blast's biggest strength is its quick activating attack chain (ice bolt, ice blast, bitter ice blast) and with stacked siphon speed you can keep cycling these attacks giving you amazing Single Target Damage Per Second. The slows from ice also stack with siphon speed which is very nice especially in pvp. Ice blast is very end heavy but at lvl 35 your end problems are sorted through transference.
Though very strong solo you benefit greatly from teams speed boost is a great buff which turns a brute into a god 
Although not its strong point ice has some decent AoEs, especially with fulcrum, in ice storm and blizzard the damage over time nature of these powers are great with corruptors as when your enemies get low on health scourge hits in, and theres nothing like blizzarding a freak mob and killing them twice 
Although Ice/Kin is strong in pvp its at its best in 1 on 1 situations meaning for most pvp you will need to be teamed, corruptor heavy teams are amazing one of the best 3 person teams possible is a kinetics corruptor with 2 thermals. Ice/Kin with double forge (+acc +damage buff from thermal) does blaster level damage with the awesome unresistable scourge.
I'm sure someone will stand up for sonic/kin but I love my ice/kinetics

ty for the info .... sonic is pretty nice at early game and also has nice dmg how is that with ice/ ??
Ice's damage is much higher with a shorter activation time - bitter ice blast, ice blast and ice bolt can be fired off in 3.24 seconds whereas shout, scream and shriek takes 5.67 seconds to activation. Although if you are attacking the same target the stacked -res (-60% with shout, shriek, scream and screech) would increase the sonic's damage considerably making it more suitable for attacking non squishies. You also have to wait until lvl 18 to complete your attack chain in ice whereas you get shout at lvl 8 in sonic. Sonic blast also has the ranged stun which is better than the hold in ice because most people in pvp will have acrobatics and does further -res.

Well, the thing about Ice's much higher damage is basically a myth.
I've played Ice to level 40 and Sonic to level 50, so I had some time to compare those sets (and I really love both for different reasons).
Ice can really dish out some burst damage, but dps-wise Sonic is king, although those numbers get screwy once the attacks are slotted up and with kinetic speed considered (as attacks will recharge faster than they can be used). However, the -res is what makes Sonic's dps-day. You can permanently keep up the res-debuff of your three single target attacks and the stun (which should give something like -15% res each) which makes Sonic an AV/Hero killer and a scrapper's nightmare in PvP.
And the really good thing about the -res is that it boosts the damage of the whole team. With my Sonic/Kin corruptor I have seen many AVs go down in mere seconds due to a cascading wave of escalating damage.
A few more things why I think that a Sonic/Kin is a good choice:
As already mentioned the ranged stun is great. You can pick off a whole lot of squishies in PvP (with or without Acro running), prepare the finishing strike on an endurance-drained tanker or scrapper and provide some protection from particularly troublesome mobs while res-debuffing them at the same time.
One of your starting attacks (I think it's Scream in English) is a pure DoT (as opposed to an attack with a secondary DoT) with 5 tics. Pure DoTs are a good thing with IO sets around as proc chances can trigger on each tic. Because of that e.g. the Hold from Devastation has actually a 67% chance (instead of the normal 20%) of triggering with each activation of this power (with a base recharge of 6 seconds and nice damage on top of that) and a 26% chance of triggering more than once with each activation. Yes, that's nasty. 
So, which kind of kin is better depends on the kind of kin you need. Personally, I have found my Sonic/Kin to be more versatile, more useful overall and less FotM than Ice/Kin (although I know that my Ying Long has inspired some players on Zukunft to try Sonic/Kin).
If it has eyes, you can blind it, if it has blood, you can make it bleed, if it has a mouth, you can make it scream.
As far as I'm aware Scourge is calculated per Tick but PROCs aren't, they're either when the power hits or once per 10 seconds the power is active (these might be the same thing really).
I'm basing this on my PROCed Crushing Field which has 3 damage Procs in it, I've never seen any of the test subjects in Perez be PROCed by anything other than the initial impact.
Things like Acid Arrow and Freezing Rain would be way too overpowered if they did go off per tick of damage. As far as i'm aware both use the 10 second rule.

I'm with carni. I've got several toons with procs in DoT powers and never ever have seen the proc hit more then once per activation in a non-toggle.
Hi im pretty new and tried some corrs and i like /kin pretty much so i wanted to know hows sonic/ and ice/ doin with kin in:
