Dumb and Dumber wanted a different taste
The situation with D&D wanting to jump ship and hurry up the end of their writing duties with GoT so they could try something entirely different with Star Wars, reminds me of a lesson my mother taught me about not wasting food and drink just because I wanted a different flavour of fizzy drink: namely, that we had a pop dispenser in our new fridge, but it could only hold one flavour of fizzy drink at a time, and one day, I grew so anxious to try the other flavour, I simply poured out the cups of the previous flavour and put them down the kitchen drain, hurrying along the process of changing flavours. I was then denied the second flavour, as my parents found out that I'd wasted the drink because our kitchen sink had a temporary holding tank that held everything poured down the drain (until it was fixed). So I not only wasted the first flavour, but was denied the second flavour. Which I hope is what happens to D&D for messing up the end of GoT so much.
Well, I thought it was an apt analogy.
