First of all, I'm very sorry to hear of your loss.
The English phrase as I've heard it in the past is "It's not the destination, but the journey."
That being said, I disagree with its application to XIV. While it was nice to see, for instance, the introduction of a market search feature, that does not justify the game having released without it. I don't get a thrill of exhilaration from seeing Improved Targeting!!! (that still doesn't function well for me).
I enjoyed XI, and I really like the potential of XIV, so I continue watching the game's development and even playing it, in the hopes that one day it will be what I want, but as for the idea that seeing these improvements is itself a reward... That's a thrill for alpha testers, not retail customers.
