I first want to say that these profiles are amazing. I have now used them to level 6 characters to 80, made enough gold to buy flying for all the 80's and leveled extremely fast with them. For the most part (I'll get into this a little more in a minute) these profiles are almost perfect. You can't really ask for more if you have multiple RAF accounts to use.
I'll give some details of the setups I've been running and what I've found to work well:
1. My booster has been a level 86 prot pally using Singular. I have 2 other accounts that are RAF'ed together, and they were leveled to 11 each using Kick's before I started dungeoning. I have the booster fly the character to the dungeon using a 2-person mount and he summons the third character.
2. I've been earning anywhere from 1-2 levels per dungeon clear below 60 and about .75-1 level above 60. I very rarely hit the dungeon timer and when I do, it's usually due to half the dungeon randomly reseting, so it clears faster than usual.
3. I DO NOT have 3 HB keys. I only use HB to control the booster, the other 2 I turn on PQR and move them when I need to move them. I tried for a few hours using the follower profiles and they never worked well for me. Luckily with almost all the dungeons, you don't need to move the RAF characters too far from the dungeon instances.
4. I turn on looting on one character and loot all boe's and random crap to that character. Once the bags are full, I turn on looting on another character and fill up their bags. When all 3 characters bags are full, I go repair and put all the BOE's on the AH. I have made upwards of 20k doing this, which is a little less than questing to 90, but that's ok.
5. I don't do anything AFK, but these profiles were never meant to be AFK. If you don't want to babysit, this method of leveling isn't for you.
These are the problems I run into in each profile:
1. Wailing Caverns works amazing. I wouldn't change anything about this profile.
2. Blackfathom Deeps, there's a murloc at the first pool that the booster should pull. At the starting levels of this profile, that murloc can sometimes aggro and kill the RAF characters. Other than that, great profile.
3. Razorfen Kraul is great as well. Only thing I would change is there is one Quilboar that the profile misses always. It's on the path up to the bosses that are split onto 2 platforms. On the left in the first platform, the bot doesn't move in close enough to pull that quilboar in the first hut.
4. Razorfen Downs, don't change a thing. This was great when this profile was added.
5. In Blackrock Depths, the booster will sometimes get stuck on the tables in the East Garrison. a simple jump will fix the stuck, but the pathing here could use some work. I use a Tauren character, so this may be part of it, but my character will get stuck every other time I run the profile.
6. UBRS, there are several several issues. Sometimes the booster will not hold the tower long enough that spawns the adds before the fire boss. If that happens, the profile bugs and you have to reset it. During the Rend fight, the third wave of adds don't get pulled, and you have to wait for them to finally aggro onto the tank. It would be nice to have the tank clear the egg room for the Leeroy title as well, but that's more of a request than a gripe.
7. Hellfire Ramparts, the second boss isn't being killed. I thought the profile was going to be changed to make it so that boss gets killed as well. The last few attempts I tried, the last boss wasn't getting pulled or killed either. All the first 5 or so packs should be killed before the long kite begins. Sometimes those mobs will reset, come back and kill the RAF characters.
8. Blood Furnace, during the second boss, the pathing was changed here. Sometimes the tank will miss the third pack because the pathing is moving the tank near the bosses door and the mobs will run and kill the RAF characters. The pathing should keep the booster near the first door instead of second door. When that third pack gets missed, the pathing breaks again and the dungeon has to be reset.
The rest of the profiles work great and don't need any changing.
