ZG boosting / rep farming at level 51

So I just bought 4 boost runs in ZG as a level 51 rogue. My rep is now 832/3000 neutral with Zandalari and I went up 7 XP bars. This mage charged 20g per run and they say at 55 the exp is a lot more. Was a little low for me because of my level. So this means you can buy runs and earn the rep you need for the epic gear. One of them said there are Youtube videos about it now.

60 Mage farmed the tigers and cub patrols. So I think with the right rep, I can complete the quests down the road and get my tier set without sweating dinging 60. There was a level 1 in the instance too by the way. Used em to help summon us in. Run time was around 9 minutes per.

The bit about Level 1 is interesting, I'm curious if the rep from mobs will go into Revered to Exalted. Generally, that is only reserved for boss kills to get Revered + rep from mobs.

Now were the level 1s inside the instance, or just behind in the area where the portal is?

Level 1s were inside, past the portal in. The 1s were used to port us inside.
