I'd rather start in orbit. I like being able to login and see what the weekly/daily is before I select my bounties.
I can see the merits of having an option to pick your initial start point like CoD.
I think what our not so kind community manager (pretty out of character by the way... not like him to lose his temper like that as far as I can tell from other posts I've read) wanted to point out is that it is most proberbly not going to happen.
You see the orbit screen is the part of the game with the lowest amount of communication between you and the servers. At least this is what I learned about it when asking myself the same question about loading into the tower.
This is why you get kicked into orbit more than completely out of the game (if there is no PSN related problem responsable).
Basically you getting kicked into orbit is because of the servers and you being kicked out of the game is to blame on Sony, MS or... your internet provider.
I could be wrong there but like I said this is what my research brought up.
I think the best route for this would be to still start in orbit however allow you to pick up bounties off of your companion app. This way you aren't wasting time if that is the only reason you need to go to the tower and those who want to jump straight into action can without having to add an extra step.
