Sorry this wasn't going to be thread about fixers defence and not about how well a fixer can compete against soldiers, I never killed the best ones alone anyway (I think so atleast).
I was responding to Heartless post first.
Firts of all, I seldom get killed by a Soldier using only a Dshark, on a one on one situation and I don't do duels since I dont find it interesting and my tactics would probably piss alot people off. ;-p
It's As from Kec3 that does the job + regular hits.
I can hotswap 5 things to get more defence against a soldier (the loss of AR against soldiers are not that important), Master bracer, Infused defender, Ring of Summoned Terror, Global def 3 and Cross Dimensional Gyro of Gemini. This would give least than 6% more def in Dodge counting that I have ~4.6k base and atleast Limber runing.
On top of that an extra 1.7k HP that would alow me to take a few extra regular shots, but it would make my hots heal AS'es worse.
(I could use Sandy bracer instead of master bracer to avoid the HP gain, Defencive luck ring instead of summoned terror and keep Infused vision preserver in Util3 at all time. I tiny bit less def but no HP gain)
It's just trox soldiers, during MR, that regulary can pull a hefty shunky of HP out off my body with Burst, FA and some regular hits in a row. But that's something I'm prepared at.
