Help with my warrior

[Skittlez]

Okay, so with my gear my Dark Elf warrior stats are as follows right now..

STR-121
STA- 95
DEX- 148/168 (w/ and w/o Shimmering Partisan)
AGI- 107

AC- 787
ATK- 815

HP- 1424

Okay, so I know my stamina is pretty low, but lets ignore that for now, so far I have never needed more it has felt like, at least not yet.

Most my gear consists of Tier'Dal Adamantite enchanted plate. Makes me look like a blueberry.

Anyway what I want to know is.. Should I be Dual-Wielding my SSoY's or should I use one in my main hand and use a Shimmering Partisan in my off hand? +20 dex on a pretty hard hitting weapon is pretty good to me, but what do I know, lol. That's why I am here to ask all your pro warriors. I don't ever use 1h weapons when I solo, it's specifically for group tanking so that's why I need to know. I have two SSoY's but if the +20 dex is better while just using one SSoY then I could use the plat I could get off one. What do you guys think?
