This post will contain nothing but facts, so if you disagree, it's because you hate facts and American and are therefore a Communist. Europeans, you can just move along right now, along with anyone not from real America.
Rogues thrive on world PvP. By world PvP I mean people who are either afk or at half health while fighting ten mobs. With the addition of guards and sanctuary cities, rogue PvP became harder, but thanks to vanish could still be done. Then came flying mounts. By the time Blizzard added teleports to instances, rogues were all switching to sword specialization in order to get the highest possible DPS. While commuting seppuku.
This lack of world PvP also hurts everyone else. With a safe, carefree, or should I say, carebear, world, no one has to pay any damn attention. Situational awareness has plummeted. When players fall out of the habit of spinning their camera and character in circles to watch for rogues, or on some days, warlocks who will fear you into even more mobs, it's not a surprise that they also lose track of things like adds, fire, and adds on fire.
But how does world PvP come back? Simple: make it.
The fact is that world PvP cannot be based on any sort of encouragement or positive effect. Small rewards didn't make sand, I mean Silithyst, any more fun. Significant rewards will only work for a short time, until we outgear them and no longer care. There is only one way to cause world PvP: give us no other choice. Put summoning stones in vulnerable locations, such as anywhere, and make it impossible to summon from outside to inside an instance. Remove teleporting to dungeons. While you're at it, put a bunch of instances all in the same area so that inevitably players will run into each other. Or at least so rogues will run into them.
Getting chain-ganked by rogues also hardens players, giving them the strength to deal with wiping continuously for hours on end. After all, I've killed some bosses in less time than it takes to run from Thorium Point to Blackrock Depths while a raid is gathering for Blackwing Lair.
Carebears have also ruined gathering. It used to be that a mineral node was a serious deal. People might fight for days over a regular thorium node, until finally someone won Alterac Valley. Gathering used to be hardcore. Dismounting to mine or pick herbs meant you were vulnerable to someone else coming along to kill you. Now everyone is spread out and not flagged. The greatest happiness came when I switched back to PvP and got into the habit of killing anyone who even dared to glance at my ore.
Carebears encourage bots, leaving them free to bot away at bot activities such as botting. If instead they were killed on sight... Let me put it this way: I started this post talking about hating America and Communism and here's where it ties in: bots. The economic growth in China is not due to stealing jobs. It's due to stealing spawns. That's right, bots and gold sellers in WoW account for over 75% of China's increase in GDP over the past five years. Kill the bots and we'll stop those damn Communists right in their tracks as they attempt to sell us gold at market prices.
