So, I will skip the pointless bickering in the post and move onto the actual information you provided.

Group content that gives everyone something to do and is not repetitive/dull/etc.
And then you use WoW as an example. I played WoW for all of 6 months (not a fair amount of time in some peoples eyes.) But in all that time I ran into...maybe 5 group quests during my repetitive/dull quest grind in pursuit of level 85. 1-85...and I only had to interact with other people 5 times IF I could even get them to interact with me.

Grinding quests, group content or solo, can be just as dull and repetitive as a grind party. Mainly because the developers seem to think that "Go out an kill 10 of these" is a fun quest, especially if they just rename the mobs and increase the "difficulty" as you gain levels. Most of the group questing I ran into on WoW were those mini-arena battles where you defeat a few tougher than normal foes and you get gear at the end. All of those followed the same outline, just different dialog and different mobs.

And in the time I was partied with those few people for that...20-30 minutes...I made no friends, everyone got what they wanted and off they went.

So I ask you kindly: What kind of group content would actually be engaging and fun and not a grind? Because if you do quest after quest after quest...that's just a different form of grinding. It's no more engaging or fulfilling than grinding mobs for exp...because really the only difference is that there's a quest NPC to start and finish it with. You're still killing mobs. lol

Don't bother mentioning Raids. It's fairly obvious FFXIV is going the raid rout.
