Well, they do listen to player complaints and feedback - things deemed “exploits” and “unfair gameplay”
You just have to have picked the red character background at creation screen.
PvP changes have absolutely occurred - all in favor of one faction. Features that 100% existed in Vanilla.
Naturally it makes business sense, there are more people who play Horde, especially in the areas where the changes were concerned. Furthermore - making things easier on the “dominant” faction makes reaching out to that faction (which has a stranglehold on retail) - much much easier.
That doesn’t make it any more fun for the faction who has an effective 0% win rate in a particular battleground - and it certainly doesn’t make the queues for the other faction any shorter.
That doesn’t touch on Devilsaurs, Layering, approximate server size etc.
This game is an rough approximation of Vanilla, where everything is drastically easier than it was 15 years ago due to changes, knowledge, and min/max culture.
This game is not difficult. It’s arguably more casual friendly than Retail. Every time you log in - you can make meaningful progression on something. Content is in absolutely no way challenging.
