Well yea, so your success came down to a good theurg basically, which is the case with just about any alb group. I'm still deciding between arms and merc for live, played merc in the beta and did fine once i got prevent flight, was tough before then. I can say that PF is godly on a merc at this patch, my target was more or less permasnared from it even with just me attacking... but the alpha strike of an arms + soldiers barricade is very tempting, and you can play deftank when required too... jury's out!
