Corr vs Def on sonic

Which one does more damage a sonic/sonic corr or sonic/sonic def?

Many thanks

The defender has a 20% resist debuff vs 15% for the Corruptor. Solo the Corruptor will probably do a little more damage against hard targets due to Scourge, but they'll be quite close against weaker targets. On teams the Corruptor will do more personal damage, but the Defender will cause more total damage to be done thanks to the stronger debuffs. Every Defender debuff will essentially boost the team's total damage output by 5% more than the Corruptor will, and 5-10% of the team's damage is going to be more than the difference between Corruptor and Defender damage, and on hard targets more debuffs will be stacked which will offset Scourge. Add in 7.5% more resist debuff in the Defender's Disruption Field and Sonic Siphon and I'm pretty sure the Defender is the better choice for teaming even before factoring in the stronger resist buffs.

I'd highly recommend a Defender for this combo.

Both powersets have significantly better debuffs for the Defender, both the -Res and +Res in the shields.

Something else not mentioned Defenders tend to TAKE and benefit more from leadership powers, assault and tactics giving them slighty more damage and to hit than corrupters .

If I have fast recharge, would the -res from the same power stack with itself?

Yes.

Personal take on it: Defenders do indeed have higher debuffs, but the chemistry of all the -res paired with scourge is golden. It takes several attacks and layers of -res for the debuffs to reach full potential, and usually the target is about dead when the scourge hits. But boy, does it hit! On hard targets, however, this shines like nothing else. By the times you've hit scourge territory through your attacks, the target will have every bit of -res that you can give layered on them. This means that when the scourge hits its damage is almost unavoidably magnified by all your debuffs. This means that a sonic/sonic corruptor is extra handy in boss battles.

I love having sonic (blast or buff/debuff) on my teams BEING USED, regardless of the AT of the user. It makes me sad though when some defenders and corrs are reluctant to use Howl because of agro concerns. Sonic Blast comes with its own safety net in Siren's Song. The heal Sandman (I think) proc in that makes for a handy spot heal on agro'd large groups. Siren's Song is really almost unfair (especially in soloing). I love getting Disruption Field on my scrappers. Stuff just melts. Particularly brutal with PBAoE scrapper (e.g. Spines/Fire) and tank builds.

Ah, thanks all.

Just one more thing: does the -res from the blast apply before the damage deal or after?

Thanks again

After. Seems unfortunate, but it's not doom-worthy =)

At a glance, I'd really think it's a wash, but I'm leaning toward Defender.

I love using the modifiers to give a base line for different sets and ATs and that. It's a little harder to call in this case, but I'll try anyway.

Let's call Scourge a 30% increase in damage, which is very reasonable while soloing. If you take advantage of Scourge on teams and purposely target lower HP enemies, or have a powerset that takes a few seconds to prep with debuffs and you're only attacking hurt enemies anyway, it's probably worth even more.

Now, how do we call the average resist debuff? It's really hard to say. I would personally call it 2.5 attacks worth of debuffing, and one instance of SR's debuff (either disruption or siphon). For Defenders that's 80%! For Corruptors it's 60%.

Damage then looks like this: Mod*(1+Enhancements+Vigilance)*(1+Scourge)*(1+Resi sts Debuff)
Corr: 0.75*(1+0.95)*1.3*1.6 = 3.04
Defender (solo): 0.65*(1+0.95+0.3)*1.8 = 2.52*
Defender (teamed): 0.65*(1+0.95)*1.8 = 2.28

*- Note that the Defender solo is only going to pull this off against ST, lacking an effective use of Disruption Field

That's incredible for either of them. On a team, the difference is 0.76. Using the same method and reasonable estimations for the value of Defiance (+30%) and Fury (+120%), you will only need 2 Blasters (2.53), Scrappers (2.41), or Brutes (2.36) to make up the difference. Because the difference of a -60% and -80% debuff applied to their damages is close to 0.5. Though the lower max targets on Scrappers and Brutes might make it closer to 3 of them.

Of course all of that is circumstantial. ALL of those variables are going to fluctuate. However, if the average only calls for 2 (maybe 3) damage dealers on your team, and you will actually have 7, the Defender is going to contribute far more damage than the Corruptor most of the time.

Defenders also get higher defense values in their power pools, and will contribute more resistance to the team. Defender wins hands down if you intend to team at all.
