I'll mostly chime in with what others have said regarding the usefulness of a pure healer. That being said Defenders come in a wide variety of styles and some are definitely more support oriented than others. In general you still want to use both of your powersets but if you want a more support focused character than you can pick a secondary that enhances your defensive abilities. The blast sets that defenders get as secondaries all deal debuffs to some degree or another but some are definitely more defensive than others. The two best options there are probably Dark Blast and Ice Blast. Dark provides to hit debuffs with all of it's attacks so every time you attack you are making it harder for enemies to hit your team, it also provides a decent chunk of control. Ice Blast has speed and recharge debuffs, these aren't quite as useful as Darks debuffs but they do reduce incoming damage and Ice has several holds along with being able to use Ice Storm for area denial as well as damage which balances it out a bit.

Enemies in this game can hit very hard and an ounce of prevention is worth a pound of cure and stopping the enemies from hurting your team is much more effective than scraping them up afterward.

Regarding Empathy the heals are the early powers in the set and they are useful at the lower levels. However as you get into the late 20s and the early 30s you'll notice that you need them a lot less (unless you join a really bad team). At that point melee characters have the slot and enhancements that they can handle a lot of the incoming damage without help there are exceptions like an Ice tank in a defense debuff heavy situation but for the most part they don't need a lot of help unless something goes wrong. Similar other support characters (Defenders, Controllers, Corruptors and Masterminds) have the slots and enhancements that they need to beef up their powers to be the primary form of team support. At this point the primary job of an Empath shifts from healing to using buffs (primarily fortitude) to ensure that healing isn't needed. With that in mind here's my general advice on buffing:

Clear Mind: If you've got the time to cast this on non-melee characters then it's worth doing but it's also reasonable to leave it until someone needs it. If you've got a Force Fielder, Sonic Resonance or Trapper on the team then they'll provide an area mez protection buff for everything except sleep so Clear Mind isn't that important although if you're facing enemies with sleeps it can be useful to toss it on the Sonic or FF character to stop them getting slept (which would cause the shield to temporarily drop) the Trapper doesn't matter as much though (since their shield is from a pet).

Fortitude: At lower levels you'll probably want to stick this on the Tank for the defense buff. At higher levels he shouldn't need it although if he's taking a lot of damage slap it on him anyway. If the team has a character with shields (Sonic Resonance, Force Field, Thermal Radiation, Cold Domination) it's worth slapping a Fortitude on them to bring their defenses up to par with the rest of the team. Other than that slap it on whatever character is taking damage or a high damage character (generally Scrappers, Brutes or Blasters). In general you should be able to keep it on up to 3 or 4 people at once depending on your build.

Recovery Aura & Regeneration Aura: These are team buffs so use them pretty much whenever they are up, the only exception being don't use them right after a fight ends, wait until the next group. Some Empaths like to call out a warning before using them so that people can gather up a bit but it's not essential. If you're on a team with multiple Empaths make sure to stagger them, having single auras up twice as often is much more useful than having double auras for the same amount of time.

Adrenalin Boost: The best use of this buff is heavily debated . Some people prefer to use it on a damage dealer like a Scrapper, Brute or Blaster to allow them to use their AoEs a lot more (and in the case of a Blaster their nuke). The other approach is to use it on a support class that has very powerful abilities on long recharge times to allow them to use those abilities more frequently. If in doubt, spread it about and see who makes the best use of it . The one exception is if you team with another Empath I strongly recommend using it on them; two Empaths AB'ing each other get excellent uptime on their Auras and can keep double Fortitude on most or all of the team.

With that said, welcome to the game. If you want information the wiki is an excellent resource:

I'll look into it a bit more when you post the full build but a few comments:

1. Focused Accuracy is really not worth the Endurance it costs to run. If you can find a spare power choice for Assault then Tactics is far superior. If not stick a second slot in CJ and use a Kismet IO, you'll get about the same benefit.
2. Why do you put off Seeker Drones? It's one of the best powers in Traps, at the very least I'd say swap it with Trip Mine.
3. Your general slotting strategy seems a bit unfocused, I'll need to look at the numbers but it looks like your defense is to spread out to really be effective.

Regarding your tactics that won't work as well as you hope. pulling enemeies onto PGT means that msot of them don't get held, you want to pullt hem to you and then use PGT. Although personally I recomemnd using seekers to eat the alpha and then jumping into the middle of the spawn. Personally I wouldn't even bother mucking about with Time Bomb when there are so many better options available but if you want to go for it.

I'd probably watch it however it's not what I'd want. I'd like to see the series rebooted with a new actor playing Indy (my preference is Nathan Filion).
