[quote name='daschrier']I can't seem to figure out how to use heal potions in battle...if you actually can that is.
Also, I haven't gotten far enough for the geonet portion, but is it possible to do online quests with random people, or do you need to have friends on your list to start a quest?[/QUOTE]
press up on the D-pad until you come to the string of command slots that has the option to use items, equip, or transform. healing potions should be at the top of that list. The easier thing to do is to set someone else in your party to heal for you. My character is a healer so I just have him heal everyone while I play with leonard.
And yes it is possible to play with random people. The very first attempt I made at playing with people ended in me getting called a n***** within 15 seconds of joining the game because my character was black. I hate people.
