It's a possibility that the raid leader has the mentality that all things must be done together but I find that could be detrimental. When I did progression, the mentality was that once your raid week is done and there weren't any more scheduled raids with the group that you were free to do as you wish. Practice to clear. Clear. Don't raid at all. So long as the group's progression was not hindered (ie chests) then it was actually for the better. You bring back possible tips or suggestions. You yourself in that clear might have gotten upgrades etc. Maybe there's a better way to handle the mechanic than you thought. Maybe they can be using a different aoe heal.

It's also a possibility that you are now seeing a very different mentality about how your group should progress and that this may be an indication that you will in fact not get along with the raid lead.

I'm not sure if your words are correct or if you thought you used the correct word but didn't... How'd you get 'goaded' into progressing? Did you not want to?? If your scheduled raids aren't done, yes you messed up.
