Hiya,
My personal opinion is that template is very ambitious.
I get you having the parry, very necessary these days with dexxers dominating all.
I get the fencing, chiv also.
I'm not sure SW can add much to that template - I use a pure Mage SW, no dex, 200 mana, full mana regen and meditation, I have a PvM SDI suit, and a PvP non SDI/defensive/eater suit etc - and the thing to know about SW is it is hugely mana intensive, it uses a lot.
It has nice spells, but they don't add so much to PvP, it is useful in a team, where you can add variety, but it uses a ton of mana, and a lot of the nice abilities have big cooldowns, that you can rarely get right for that PvP moment.
I'd probably take the SW off and go with something else, unless you have the mother of all suits.
Poison as this is OP right now (and take off med for healing/anat)
Or Magery for less mana intensive more flexibility.
