I wish I could still use glider. After that huge lawsuit was finished, they took the glider servers down and I just sorta stopped after that. There are/were plenty of other bots but nothing that looked nearly as easy or as good as glider did. And I agree with you that botting was even more addicting than actually playing the game regularly, which is something to say for WoW. I was always too scared to actually use glider/pather in bg's though. I strictly used it for leveling up to max and then farming for items/gold in remote areas. It was always very tempting to go into bgs though especially once they let you buy the epic gems from honor points.
Yeah I spent countless hours setting up Glider for BG's. It actually played my rogue better than I could, until black Tuesday when everyone got banned after the sneaky Warden update in May 2008. Now I just make hundreds of thousands of gold playing the AH, and doing arena.
