With the WotLK timewalking event being live our group of 4 got it out of the way. One of our dungeons was The Nexus.
We decided it would be fun to take the right path at the very start instead of the left (Don't know about other regions but on EU the left is the status quo). It felt like a whole new perspective on an old dungeon. The pug we were with was very confused and disorientated but it was a blast doing something that wasn't the norm.
If you ever get a chance to do the nexus and you're leading the charge, go right. If you've not done it before you'd be surprised at how different things feel.
I want you to share stories of things you've done in a way that throws out the conventional method.
