Since this game has odd and often inconvenient ways of blocking simple functions (like partying or whispering for examples), I was just wondering what kinds of things can you NOT do during duty finder waiting?
For example. Me and my significant other were playing together and we signed up for a dungeon figuring it was as simple as partying and having the party lead sign us up for group finder. Well...it said 2/2 on DPS (her as THM and me as ACN) so we thought it worked. Well it said 1/2 DPS on her end. When I put my pet away it worked for both of us so apparently one Don't is do not have your pet summoned when playing as an arcanist while signing up for group finder lol
So forum community, I ask, what are some things you can NOT do when signing for duty finder so that it will not split you from the people you are trying to sign with or cancel your participation in the duty finder. Some more specific questions are below~

1) Can you change classes while waiting on duty finder to match you with others?

2) Can you change maps?

3) Can you view cutscenes (like turning in quests or talking to NPCs and such)?

4) Can you participate in FATE's and Leves?

Feel free to mention anything else about what you cannot do, those were just my four questions :3
