I'll catch some clips here and there but overall, I am of the opinion that watching (and I mean actually sitting through a whole stream) someone play FFXIV is extremely boring. That said, I do understand how some might like it, and especially the case whenever an Ultimate is released and it's a wild race to the finish line. I think that, in this regard, a spectator mode is fine... just gotta work out whatever kinks exist in the coding and weed out anything that could be exploited by players.
