The game is essentially like ffxi merit party when grinding. Yes, people do form grind parties other than leves. With xp chains, there is a motivation to keep that chain going and to chastise that noob who broke chain #399. It makes people want to perform better rather than just spamming. Small things like missing a skillchain or magic burst, someone with crappy gear missing a lot, and a damage dealer not eating food actually matter.
Right now, nobody buys food because it doesn't matter. People just do whatever they want because it doesn't matter when most mobs, that's not an NM, die within 5-10 seconds with or without using weaponskills. It's good for people who envy the "elitists with big e-peens", but it makes the game very boring, and non-challenging. Catering to WoW players really ruined ffxiv. The best WoW players are the noobs nobody invites in ffxi, so they couldn't hit level 75 after so many years of shouting in jeuno and aht uhrgan and dealing with GMs.
