I've been in a few batttles where the commander has given up his slot for a good player instead of removing someone else, which is something to condsider before removing it.
Commanding from spec isn't ideal and stops the commander from seeing how much gear is left and also stops them from setting battalion flags themselfs.
Obviously in spec people can see what the ememy is doing, but i've never heard of anyone sitting in spec just to call out what the enemy team is doing or the locations of hidden players. Personally i'd rather be in the battle having fun and getting exp.
I do like the idea of having fixed camera when dead, but as smoothrich said strat battles can be rather entertaining to watch for a spectator. I am actually sad enough to join spec, when i get home from work and theres an ongoing battle that i'm too late to get into.
Also nobody called out your location, i was there, just unlucky i guess
