Breakfast Topic: If I had an in-game TARDIS of my own

If I were the Doctor and had a blue police box that was bigger on the inside, I'd travel around and correct various mistakes in my life without much worry. (Never mind how the timeline doesn't really allow this.) Forgetting to get up on time from my nap so that I delay my guild on their first Illidan kill? Never would happen.

Or how about that time I wiped us on Archimonde because I went in with my DPS gear on instead of my tanking gear?

Or that time I face pulled Ultraxion before everyone was ready.

And that really embarrassing time on Ragnaros when I kept DPSing down the wrong add and getting mad at everyone else for letting adds through. Or that other time on Rag when I went in and tanked without my fire resist gear on.

Or that time I moved on Aran.

What's the biggest moment you'd go back in time and correct in your WoW life, if you could?
