When I saw the title, I thought this meant no reloading at all, and starting a new game if death occurs. That's not something I'd do the first time through, although it's a nice challenge on later playthroughs. Probably not something I'll do at all in Inquisition, in fact, since I usually reserve that for games where I can create the whole party and where party members will stay dead.
I never reload to correct mistakes that were made in character unless they actually render the game unplayable (some games, for instance, you can end up turning every NPC in the land against you by clipping one of them with a fireball, and then it's not possible to finish the game). I will occasionally reload to correct an out of character mistake -- if I accidentally selected a dialogue option I wasn't intending to select, for example -- but otherwise I reload only if the game would otherwise be ended. Reloading for angering a companion or getting a poor outcome on some quest, however, is not something I'd ever do. Goes completely against what I want out of a roleplaying game. Heck, I like screwing those things up now and again. Makes things more interesting.
If the dialogue wheel/paraphrasing causes something that I did not intend, however, I count that as an out of character mistake (likely one causing the character to act out of character, which I will certainly reload to prevent). Hopefully I won't have to this time, but the threat remains.
