This again.

The only fair way to deal with this, deciding to use the dungeon finder tool (agreeing to be put together with a bunch of random people with different opinions and goals), is to let the majority rule. If you're in the minority on either side, suck it up and stop being entitled. If you absolutely insist on enjoying the game a specific way, you should make your own group, and not pair yourself with completely random people, risking being the only one who wants to enjoy the content your specific way.
