People are disappointed for 3 main reasons: No hexing, No Looting, No old school TC. This is enough to ruin the PvP experience. And those who were mainly doing pvp are lost now.
When season 3 started I was all randy, wanted to try out what had been advertised for years. I created a character, escaped the tutorial thingy, and then found out that crafting had became a pain in the ass. All my hopes where that I could craft without spending too much time what I used to loot. Adding to this that hexing was removed, and thus the possibility to fight multiple opponents by using environment and timing, which make farming safer and faster (also NPC drops got nerfed hard). So, I had little time to play, but there was no shortcut to acces gear, at least not the few I knew from before. Well, the only way to advance in the game was to do time consuming quests and shit like that, but that's not why I was playing the game in the first time. I almost don't know anything about the quests because I never did any. I would just kill NPCs, science everything, craft basic gear, then go kill someone to get better one. Once I have decent shit I would join for larger scale PVP. From what I've heard, TC isn't a thing anymore, more like the militia bullshit I hated so much.
To sum up, the game I love was the perfect balance of a month of farming that would last the rest of the session of endless pvp (I always looted a little bit more than I lost on average). It seems this game no longer exist, I feel like when 2238 closed: "it's over, go do something else".
The features that kept me entertained are gone, and thus, so am I.
