My first experience as a tank - I thought I was playing WoW for a second

I'm sorry if I misunderstood you, but your first words were literally "New player".



Yes and no. FF14 is a multiplayer-game and a dungeon needs you to cooperate with at least 3 other players. So you have to work together and do your best to beat that dungeon. To ensure this, you have a task to do defined by your job-role - so no, you can't just play how you want, you have to play in the best interest of your group. And they may kick you, if you don't.

By playing slower, I don't think I'm endangering the group as a whole. If people want to speed run, they can create pre-mades with their friends and faceroll the whole thing.
I don't buy at all what you're saying.
