Okay.

So, having been on an extended break, I'm now getting my stuff back together, and I've gotten to the point where I'm trying to work out what to forge/improve on next.

This is what Caedryn's loadout looks like right at the moment:

Armour

Fullplate: 107/110
Greathelm: 89/90, 71/101

Swords

Katanas : 106/414/239, 132/259/280
Claymores : 328/430/127, 360/251/171
Greatsword : 184/508/162

So, what am I missing? Any thoughts?

You good with the max speed katana.
One of those claymores is great for fast damage, but horrible for wounding. It'll work wonders on squishier targets.
I think a little bit faster greatsword, in exchange for less damage, would be better, especially since you have a high damage weapon. The wounding is wicked on it, but it isn't fast enough to keep up with the wounding.

The 89/90 greathelm is the better of the two, and the fullplate is great.

Wow you lied to me about your greatsword.

Some guys always lie about their greatswords.

I sold that, this is a new one.

The greatsword Shrimp-boy is talking about was about 106/501/181 IIRC.
