This is completely true if you're a character with good single target burst damage, but on a FF/DP defender your best method of keeping your team safe will be through defense buffs. If you want to quickly remove a dangerous target, your best bet is to use suppressive fire to immediately remove it from the fight. Death is the ultimate debuff though, and if you want to utilize it your best bet is with area attacks. If there's another person on your team with decent area damage, the two of you can pretty quickly remove most of the minions from a fight and take a lot of pressure off of everyone else.

If you're worried about slotting, I can throw a build together for you. I just need a general idea of what power pools you're using and what kind of price range you're looking for (SO, cheap IO, expensive IO, purples, etc)

One of the things you want in your remaining three slots is one of the ancillary armors that offer resistance.
Repulsion field is a pretty nice power. The end cost is nasty, but it has a pretty good sized area and can seriously screw up melee critters.
You do want to go for area attacks. Force field is a fire-and-forget primary that will give you a lot of time for blasting, and the most damage you can do will come from spamming area attacks all over the place with fire ammo.
You've taken all of the must-have defense buffing powers from force field, and you're a defender, so I'd say you definitely have "enough" defense buffs. If you want to really go the distance pick up maneuvers. It's more useful to you than perhaps to any other type of character in the game.
For IOs, one big thing you want to focus on is procs in your attacks. Dual pistols can take a lot of them. One you really want to go for is an achilles' heel proc in the basic pistols attack. The only reason you wouldn't want to do this is if you were using thunderstrike in it. The two types of set bonuses you want to be going for are defense and recharge, but how much of each you get depends on your preferences. You could soft cap your ranged defense without making too many sacrifices.

Here's a chart I made to show how effective each power is at stacking debuffs.

dual wield: 3.6 debuffs
executioner's shot: 3.1 debuffs
piercing rounds: 2.4 debuffs
empty clips: 2.4 debuffs
bullet rain: 3.3 debuffs
hail of bullets: 1.9 debuffs

It's possible to keep three stacks of -damage going if you keep the basic pistols attack out of your attack chain (which will hurt your damage output and put a strain on endurance) but this is 37.75% damage debuff for each defender, so it can be worth it in situations like an AV fight.

How serious are you being here?

Well, maybe YOU don't. :P

Only one challenge at a time. And Targutmonkey requests that no one challenge his team for awhile while they get stuff together.

Haven't people been banned from PERC events before? And stop using the word discrimination, because that's not what's happening here. Discrimination requires action being taken against a person based only upon what groups they belong to. If people were refusing entrance just because they weren't from Pinnacle that would work, but there are other reasons here.

- The intent behind "captain run league" is basically "the captains can do whatever they want as long as most of them agree to it". Quibbling over whether or not the captains are allowed to do something isn't the direction to go.

- Lots of events have a list of people who are banned from entering. So what?

- I have no idea what you mean by "We will pull all prizing and PvPEC support". Can you explain this, because I had no idea there was any PvPEC support.

There was a lot of weird confusion or summat. Omega asked Nymph to do it first, but someone didn't want to do it that way since Nymph and Omega were on vent together. I just stayed out of it since it didn't matter.
