Whats the worst rep grind ever? For me it was Skyguard. I know it can be done in like 12 hours if you just power grind mobs and kill the minibosses along with both the dailies in Blade's Edge and Terokkar but it took me forever. Then I got seasick when I finally rode the damn things lol. I would say the one for the Nether Drakes but I gave up on that crap at honored.
Not sure if Kurenai or Kalu'ak was worst... Doing those daily quests which required flying from Howling Fjord too Borean Tundra was a pain in the ass and all for a epic fishing pole with underwater breathing... Though cant say for sure since TBC was a while ago and cannot remember how long it took to gain exalted by killing ogres and delivering beads..
Getting the "Hero of Shattrath" achievement wasn't hard, but it was pretty mindnumbing.
1350 basilisk eyes, each with around a 30% droprate or something. Got it done in a couple of days, far quicker than many other reps I've decided to grind, but holy christ was flying around Terrokar shooting basilisks mindnumbingly painful. And that was just to get to neutral, had to use my entire accounts supply of Scryre rep gain items afterwards to hit exalted, and I've been keeping hold of them since TBC was released, leveling multiple characters etc - still ended up having to go to the Mechanar to farm a few more items.
Killing millions of pirates back when you needed Bloodsail rep at honored AND Goblin rep at exalted at the same time to get the Insane title was pretty memorable too. Can't say it was the worst grind, since I enjoyed it as bizarre as that sounds, but it's memorable.
Timbermaw Hold or Winterspring Trainers in vanilla.
Yeah. That was a horrid grind.
I agree about wintersaber trainers. I did it at a time when each quest gave 75 rep and I hit exalted about a week before they decided to make it 250 rep per quest.... If i'd know that was happening i'd just have waited.
Nat Pagle, though not a rep, was pretty grindy and miserable toward the end there.
I for sure hated AB more than WSG. I didn't mind insane all that much, though I did end up paying some guy like 70,000g back in wrath to sit there in my group and aoe tanaris pirates for goblin rep while I semi-afked reading a few books for class over a weekend so I guess I couldn't have liked the cartels much. IDK.
