I'd like to try to put this in perspective for you:
These are the balance changes that perhaps should've happened before they started Season 5 of the Feast. SE is on record saying that they didn't get enough data from the preseason to facilitate any balance changes (furthermore, it was because they were largely focused on making sure the raids were properly tuned), but decided to start Season 5 anyways. . .
Now imagine if that were the other way around. They balanced PvP then said "we didn't have enough data/ran out of time to balance the raids. Please try them anyways!" and simply left you to it for almost 2 months. How much of an outrage do you think the community would have? How bad would it be if there were major issues with Shirogane when it opens and they just say " We'll fix it later. Please enjoy housing in Shirogane"? Because THAT is what happened with PvP. You say who gives a fuck about PvP - clearly not you - but what about something you like in game? Imagine it was left needing attention and they didn't get to it in a timely manner, but expected you to just accept it and keep playing? (In fairness, they ARE human, they won't catch or fix everything right away or when we want it every time.) Imagine someone came along and made a statement as baseless as yours about something you like, and ask yourself if that sounds okay?
I won't mince words: Your way of thinking is VERY detrimental to the health of a game, and I for one am glad you aren't a part of the development team. If it's in the game and it needs a fix or adjustment, it's worth it, plain and simple. PvP has been largely neglected for the longest time, and now with 4.0, and the near sacrifice of what even the PvP community loved and enjoyed all along, they're trying to give it a more mass appeal and show some support. It's here and it's been here for a while, no matter how much anyone wants to hate it or claim it's dead. (Side note: If you were queueing Frontlines, you missed a fun event I started simply with a forum post over the weekend. If you were queueing for the Feast, you're a bit late to the party to try to jump in ranked matches as an unranked player, and 8v8 while different IS still VERY active, for better or worse, so I challenge your claims of it being dead - AS a player who enjoys it regularly.)
Now then, for the people who are looking forward to Royal Menagerie Extreme, Return to Ivalice, or even just Shirogane, tell THEM the patch "has nothing in it" when 4.1 hits, and see how well that's received.
