1-8 Make a human hunter so you start in Northshire. Group and summon 2nd leecher and run (use Chauffeur heirloom mount) to Murloc island next to Goldshire. A hunter with heirlooms will kill the level 6-7 murlocs in 2 shots. Instant respawns here so it’s very fast.
9-10 Run leechers to the Hogger area or Westfall beach if Hogger is crowded. Make your way to the Deadmines entrance as you get closer to 10. Make sure you hit 10 before reaching the entrance or you can’t zone in. Have the level 100 meet at the entrance since the level 10s can’t use the summoning stone.
11-19 Deadmines. Leave the leechers next to the first cannon in the dungeon. Use the level 100 to round up all the trash, kill the first boss, get all the trash from the second boss area and bring all trash back to the cannon. Drop level 100 from the group and use one leecher to hit the trash in the cannon. That pull will be 2-3 levels. Leechers follow for the rest of the dungeon. Finish dungeon, run out and reset. Grab the dungeon quests and complete them after each boss kill. Leechers will be 19-20 at the end of the dungeon.
20-23 Stockades. Do the dungeon quests. Leechers follow, turn in quest to kill Hogger next to Hogger, and loot the fire boss for quest item.
24-27 Scarlet Halls. Leechers follow. You should ding 25 on your first run. Run again for dungeon quests if leechers couldn’t get it on the first run.
27-37 Scarlet Monastary. Run across the hall to the other SM instance. Run this with leechers following you. Do the dungeon quests. It should take about 3-4 runs. I am at just about 1.5-2 hours /played at this point.
37-48 Main Gate Stratholme. This will be the first place where you hit instance cap. Log after a run and do something for 30 mins. I usually plan my next set of characters. This place is stupidly good. Make sure to hit all of the additional bosses. Leave leechers at beginning, having them run out to summon the runner back to the beginning to reset faster. Should take 4 runs.
48-59 Lower Blackrock Spire. Leave the leechers at the first open area (near the ogre area). They will be able to get exp from almost everything in the instance from here. Grab the roughshod pike from the wall after the 2nd bridge and the head off the ogre boss. When you get to the skull pile up the ramp from the spiders, use the ogre head in your inventory to summon the optional boss for more xp. Should take two runs. As long as you make it to 57, you are fine and dont need a third.
59-61 Hellfire Ramparts. Leechers follow. Run twice if you can’t grab the quests the first time.
62-65 Blood Furnace. Leechers follow through the instance. Leechers loot blood and item off first boss.
65-69 Heroic Blood Furnace followed by normal Shattered Halls. If you are already saved to the heroics from prior runs, you can just go ahead to Shattered Halls. Ideally, you would want to hit 70 here, but that run back is no joke and once I hit 69 I dont think its worth all of that extra running just for the extra level
69-70 Azjol-Nerub (must be 69 to enter). Leechers follow the runner through. Should be one clear. Not worth running twice for the quests.
70-73 Ahn'Kahet. Leeachers follow. 2-3 runs. Make sure that you are completing the quests as you go through, because they are sequential and the complete message doesnt pop up properly on its own.
73-80 Gundrak. Must be 73. I love this place. Start on the snake side, leechers follow for one run to complete the quests, then I leave the leechers slightly down the ramp for slightly more trash exp. Once cleared, runner runs out the exit on the right side past the last boss. Leechers go out their entrance door. Rinse/repeat. This is usually 6-7 runs.
80-85 Stonecore. Have leechers follow until the entrance to the cave with all the trash before the golem boss/after the dragon boss. Once you are nearing the final boss, have leechers use the port behind the dragon to return to the entrance. Run out once complete and summon runner to restart faster. 5-6 runs. The quests are easy, but shitty exp so up to you if you choose to do them.
85-90 Temple of the Jade Serpent. This part probably could be improved, but at this point I see the light at the end of the tunnel and want to be done. Leave leechers at start. Pick up/complete quests without leaving entrance area. 6-7 runs.
