Tractor:
Your client fundamentally does two things:
1) Displays information from the server
2) Tells the server your updated position/what you did.
You can (and bots do) simply change your position in the zone. It's not, "Oh man, this would be really hard to implement on PS2." It's, "I changed it and now it's done." Changing the POS variable is one of the only functions the client has. It's entirely capable of doing it. The client also knows the place that tractors is being cast from, because it's necessarily within 20 yalms (casting range), so just have the client set its new position to the caster's position. It only works while dead and without reraise up, so it isn't like people could exploit it to undetectably POS hack. You don't believe me? Think about how Draw-in works. If Tractor was just Draw-in for dead people, it would be perfect.

The only reason to leave it this way is if SE fears people will somehow abuse it from a balance standpoint to move really quickly through a daisy-chain of tractor casters. I'm not sure exactly what the benefit of that would be (maybe actually getting to the top of Tor before your stone grows dark?), but this is the only real reason I could see.



As far as TOS-breaking to circumvent the issues that, until now, we've pretty much agreed plague the game... I don't know, it's like doing a slow roll through a stop sign past midnight in a sleepy neighborhood while you're driving back to your house. Technically against the law, but your life is slightly improved and no one is any the wiser.
