I think it's been pretty well said already that play style varies widely in roulette and no one player has the right to decide how the dungeon is run. As is, you're in the right, which is why most of your groups give you commendations. You will always find that one guy in the bunch who wants to leeroy and doesn't stop to see if the rest of the party can handle it, but that's what the vote kick option is for. If that person is being counter productive and/or rude, just vote kick them. If you conform to their style, or allow them to force you to conform, then you're only going to encourage that behavior in them and they're guaranteed to do it with the next group. Sometimes you have to tell those people to stand down, and if they don't want to, don't let them spoil the fun for you and the rest of your team. More often then not, if you allow them to force the team to move at their speed instead of trying to find the right speed for your group you will end up wiping multiple times anyways no matter how easy the dungeon is.
