They give us all these different weapons and ammo types making me think they want us to use them all, but it's a serious pain in the *** to switch weapons beyond the 2 that you currently have equipped. I would love to be able to use rocket launchers and grenade launchers against bosses, etc. But mid-battle it is just too tedious and takes too long to go into menu and swap out weapons. For this reason, I basically have only been using assault rifle/shotgun and sniper in 2nd slot. They are totally defeating the purpose of having cool weapon types, because nobody can even use them.

There needs to be a quick way to access your weapons. It is quite simple really. Most other games just double up the switch weapon button (normally triangle on PS3). Pushing the button switches weapons, and holding down the button allows you to access all of your different weapon types, then select one.
