I have a question about starting equipment...

I picked up a bunch of starting equipment at Bard 1.  But now I'm Hexblade 1 (Character Level 2), what happens to all our starting equipment?  Do we sell it for half?  It seems odd to do that when normally characters that start at levels higher than 1st would just buy everything without needing to sell their starting equipment.  It seems like an unnecessary step.

I'm not sure what you are trying to ask.  You can either start with the standard equipment as defined by your character class (which includes a pouch of spare change as well), or you can roll for your starting cash and then you buy all of your own equipment.  There is no reason why you would sell that equipment off again.  The system seems to just assume that financial gains for most characters up through 4th level is mostly a wash as there is no bump for starting wealth until you are starting as a 5th level character.
