School man, school.
I hate how I can't be the leader of a squad, platoon, or OIC anymore... ever since I went into Veteran Mode. I used to love it when 80% of the time I joined a Domination game, I was the OIC and was a walking, talking, shooting, health ATM.
Not to mention, being able to use the powerful abilities that are given to an OIC. 2 good OICs going at it is a very interesting battle. An OIC can sometimes turn the tide of battle quite dramatically.
Moral of the story: Don't do Veteran Mode unless you really want to switch factions.
