Idk; could be a few things
1) They know soon enough they will no longer have a voice or place to troll here due to payment so they're getting in their last few blows before they are cut off
2) Some people who have stood by SE are becoming distraught at the pace and direction the game is taking and due to payments, are really starting to let loose their tongues because they were "willing" at one time to let people talk, assuming SE would never do the ridiculous things they (the "other MMO" crowd) wanted in XIV but yet, somehow, SE is putting that crap in anyway and it's ruining the game. This in turn almost forces the hand of die hard FF MMO players into, "Do I stay and HOPE to the gods SE stops doing this stupid crap and actually works on what is wrong with this game while giving us something to play as well and I pay" OR Troll troll troll bitch whine complain QQ scream cuss QQ some more; actually make 1 valid point, troll troll etcetera.
3) The player(s) are bored. Personally, it use to be fun coming in here and reading the obligatory QQ post and comment or read an actual valid post. Now, it's more like the ones who had actual good ideas for this game have gone, for whatever reason that may be and all that is the majority and left here to post are the ones who imho, wanted nothing but things that really didn't matter in the game and easy mode like, "every other MMO". <--- This right here is why I think there is so much bickering. These are the people who don't know how to deal with another human being in a mature way when discussing an issue and because this seems to be the majority in the gaming world as younger and younger people have access to it, this is how the majority of forums and games will be. /sigh
