People like Skolver/snarb because it boosts their sword attack.
People like Skolver for its piercing defence (since the faster swords to use are the poking swords).

That said, as recon, you probably wanna think more about your offense than defense, since you have so much health to start off with, meaning heart trinkets are less useful for Recon.
Recon is both resilient and vulnerable - you have the health to take some hits, but if you get hit out of your cloak, you're probably screwed since it takes a while to regen and strikers will probably eat you if you don't have cloak.

Armors that boost your weapons are preferred (Vog, Skolver, Justifier, Shadowsun, Bombastic/Mad Bomber for bomb damage).
------
As far as I've seen, MOST Recon play tends to be either:
- Capture-based bombing (mist-type bombs, sun shards) - all level 10 bombs have max CTR by default for recon, so damage is the way to go. Sun shards are an offensive bomb, mist type bombs are defensive.
- Sword-based Assassination (high damage/speed swords + cloak stabbing, or high damage + heavy sword)
- GFL Guns (Valiance, status guns, and probably sword for backup - uses deathmarks heavily).

Recon isn't a very starter-friendly class since you'll probably end up getting hit out of your cloak and being eaten by the wolves more often than not - if you wanna keep your cloak, you need to have a good feel for how people (especially strikers) move around.

The interesting thing about recon is the deathmark - by nullifying people's defenses, you don't have to worry as much about whether or not you have the right element weapon to take people down. For example, almost every armor has Normal defense, but if someone is deathmarked, even a Sudaruska's normal attack is painful. This is especially important for gunners because of one thing: Valiance.

If you are a recon gunner (god have mercy on your soul), Valiance's knockback becomes heroic in interrupting striker movement, and more importantly, with deathmark, it becomes the most powerful gun in the world.

Here's another tip for you since you are a recon, it is to move in one direction, cloak, and head in the other direction. About 90% of the time, an enemy will aim in the direction you were heading last. While they are trying to uncloak you, just come in behind and strike.

Crystal bomb line.
Full demo set.
Fiery vapouriser line for two weapon slots (I would use shock more, though, if I had one).

If I had four weapon slots:
Blast bomb line weapon.
Crystal bomb line.
Fiery/Shock status bomb.
Antigua line for people who can dodge the Crystal Bomb - for 5*, I'd use Sentenza, because hardly anyone uses Shadow defence - or an Alchemer for the spammable charge, Pulsar line for running away, etc.
Full demo set - I'd say, pack one with CTR med in total, and another benefit (almost like Mercurial Demo, but with CTR instead? Too much to hope for.) Could use trinkets to make up CTR bonus, and use a better armour (Mercurial Set? SPEED!) Try to get shock/freeze resists - possibly use trinkets?
Fully heat all bombs.

Total benefits?
Bomb CTR Max.
Gun damage med (Query? I don't know the exact value)
Gun CTR med.
(Extra added benefit)
One DPS, one status, one sheer annoyance bomb. Possibly 2 DPS bombs - what do you count the Crystal Bomb as?
Elemental defence - consider use of trinkets for defence, or just for (up to) +12 bars extra health, or for status (see below).
(Shock and/or freeze resists, so you can walk through status traps.)

Notice, this is only my opinion, but the use of a Mercurial set with Strikers could lead to some assumptions about hacking.

Also, keep in mind that recon gives you a nerf to your sword speed. So if you're going to use a sword, stick to a fast one. I try using faust on occasion, and almost always regret it!

@Traevelliath: yes, status bombs are good, but a good gunner will hose you. They'll see the haze, and just shoot you. That's why it is a good idea to also pack a damage bomb. RSS is best choice for this. But a Nitro wouldn't hurt, it also knocks around your enemy, though it does a lot less damage (I think).
