Tear this apart for me

[ReeseFlamelocks]

Be vicious about it if you really have to. I have thick skin.

I'd first like to start that I have no idea what a lot of the terms I've seen here mean specifically, or practically, such as "Assassin," "Acrobat," or "Radiance." (They also appear to come in gradiations of roman numerals-- again, I have no clue.)

This is a three year old build, so the above mentioned phenomenons (as well as many others, no doubt), did not exist at the time.

Reese is primarily a TWF rogue that wears robes. I was using a +5 Mithril Chain Shirt, but frankly, on elite, there is nil difference between damage taken from wearing the +5 Mith or robes. So I switched to robes for the ease of switching out particular bonuses they afford mid-combat.

Listen - 15 (Yeah yeah, well it IS a rogue skill according to DnD. Who knew at the time Turbine was going to make it useless?)

Tumble - 17
UMD - 17

I was considering diplomacy, but frankly, if you are getting aggro, then you are playing the rogue wrong. Timing is key in managing aggro, and making sure you don't ever get it.

Feats (I'm going to try and pick them out, but frankly, I don't entirely remember what I picked, and what the game gave me.)
2-Weapon Fighting
Improved 2-Weapon Fighting
Weapon Finesse
Improved Critical Piercing
Crippling Strike (I think?)

Any opinions on dodge and mobility?

Typically wear a Robe of Improved False Life with the Nightforge Gorget (heavy fort).

This is not a tanking rogue, this is not a soloing rogue, this is not even a rogue that can kill anything by himself. Even against CR 10 mobs, I'm sure I'd get my butt handed to me. This is a tank-assisting group-rogue that makes sure mobs die very very fast. When a good tank gets a mob down to about 80% health, you roll in and go to town. Things on elite will die...fast. For not-so-good tanks, you wait till about 60-70%ish.

If you get in trouble, you tumble and jump away. If you have grabbed aggro, you run around. If you NEED to grab aggro, such as a mob off of the cleric, you grab it and then tumble/run around. High jump is also key because you want to get behind the mobs when your party engages.

For 360 swingining mobs such as giants, trolls, ogres and a few new mobs I've seen (like some lizard looking guy in the Planes of Twilight or an Orthan {sp?}), it is imperative to tumble-in, tumble-out to avoid damage. You have to time it well and take note of the animations that the mob is doing to prepare.

The key here, frankly, is to avoid getting hit all together utilizing tumble and jump. You go in, kill it, and then get out, quickly reasses the sitch, and then go back in. Using stoneskin and blur scrolls help. Self-healing is also a must, as a rogue such as this should not burden the cleric or group. It can be really easy to screw things up and get flattened, so if you do mess up, no one pays for this build or your play-style but you.

No sacrifices have been made in the key rogue skills, as this is one of the primary elements that a group would expect of a rogue.

Please, tear it apart and tell me what I need to fix and/or add, especially concerning perks that have been added in the last three years.

I know this is kind of long. I appreciate anyone who bothered to read it and post input. Thank you.
