The general player base needs to improve

[KDSilver]

True, true. But even the main series have fights that you can just braindead fight through. The most prominent examples that come to mind are the eidolon fights with 13, and Yunalesca from 10. I used to not include anything from the Crystal Tower raids, but with alliance roulette being as popular as it is right now, I have to include them. Sure, one could say that there are new players, but 7 times out of 10, the majority of all 3 alliances will have veteran players.

Yes, but when they are playing alone on a game X or XIII, their fails won't have consequences except for them. So they don't really care.
The problem is, if you come on a MMO with that state of mind instead of thinking as a party and your contribution for it, well we know what it looks like.

Let's checks some threads some times.
I've really seen more and more thread asking for X content to be soloed.

In the end, dev team design choice was as good as bad (good for personnal experience, cause FFXIV really is interesting to discover aside from trials and raids) (bad because less and less people think about their contribution as a whole party and are selfish)
