Why Speed Pulls?

[Sousoulsu]

So, why do I have a bad taste in my mouth for Speed Runs and Hunts, other than some of the attitudes some may encounter during those times in this game? Goes right back to WoW. There is my valid reason, for me.

I read everything you typed, but this particular bit stands out the most to me.
I agree that in other games, Speedrunning would annoy me in random groups because some of those dungeons are actually threatening the way they were intended to be done.
With WoW, there are now Challenge Mode dungeons for people to speedrun if they want to.

Your sentiment rounds off your opinion nicely; but the way XIV dungeons are designed is the reason I don't think anti-Speedrun sentiments hold any water. If trash were threatening and had interesting mechanics and the dungeon designers trusted players to be at least a little competent, speedrunning would be much less of a thing.
That said, I can understand the sentiment of speedrunning being bad, thinking back to games that actually had interesting/challenging/mechanic-heavy non-boss content in dungeons.
