Mate I'm no game designer at SE, it is not my job to provide new ideas. However I'm a tabletop RPG player and a long time MMORPG player. Also, the content of wow has been very linear since burning crusade (and I know quite well what I'm talking about).So in otherwords, you don't have an idea for innovation. The bolded sounds like you want the PvE content to be exactly like WoW's. WoW has the same exact issue of people complaining when they feel they've gone through the content btw. They just went through a year long content drought and are able to go through another. People are complaining there much worse than here.
Also I'm not complaining that there isn't enough content on FFXIV, but rather that it is mundane and lacks insight.
The fact that there are more players watching wow (or any other game) than FFXIV has little to do with GCD ... (what makes the interest of a MMO isn't how fast you push on buttons) Mundane and boring summarize quite well the situation on FFXIV.As for your stream comment, I watched Towelliee play FFXIV on stream and people were enjoying it. He even had 3000+ players watching it when he was being paid to play it. The story is enjoyable to watch. I was bored watching him play WoW doing the same PvE content and GARRISONS/SHIPYARDS over and over. This is the nature of PvE content, you learn how it works and then when you figure it out, it's now boring. Our age of social media is another reason PvE content is blown through and we have this issue. In an age where people are EXPECTED to watch videos, people know how the fight works before they even do it for the first time, thus clearing it faster. There is no process of wiping to figure out the mechanics, unless you're among the world firsts going through the content. Some games aren't as fun to watch as others as well. WoW's 1.5 second GCD would by default make the combat more fun to watch than Heavensward's 2.5 second GCD. Doesn't mean it's not as fun to play.
