Yes, yes, and yes, lol.
I also am not a fan of escort missions for similar reasons—I also hate chasing down the escorted person if they decide to run off (or worse, attack something).
Timed missions are my most hated type of mission. Like you, I get performance anxiety when I see the timer. Worse, I feel like I can’t pause and look around, explore, enjoy the ambiance, etc. By the time I leave the area, I feel like I wasn’t really there at all. There was just rushing frantically and no room for other thought or experience.
