Soldier was kind of a joke in the first game, as you could keep the maxed immunity skill up constantly and it was pretty much like you were running in god mode. Now pretty much every class is forced to use cover. But I do like the variety of weapons at my disposal as a soldier. Use assault rifle most of the time, but if I feel like sniping I can, and for boss enemies protected by barriers/shields/armor, the Collector beam weapon chews through that stuff like crazy. None of that silly crowd control and debuffing, I just get straight to the killin'!
Hardly ever use any of the soldier skills either.
