Other.
Most of the time, be it Siege, Battle or Defend the cmp, I use 3rd person view default. Nothing should be taking my awareness there in any situation.
In Strategvs battles I use a lot the zoom of the 3rd person view, specially those use Sieges with silly ranged on the other side standing still (easy targets), on the stalemate moments (beginning of Sieges or Battles, or when the distance justifies it).
edit: forgot to mention that I'm using a Bow.
