Ok, so pretty much this is just a simple guide on how to get ambassador and if you've already gotten ambassador. Getting all the PvP reps to exalted without trying to tear your eyes out of your skull.
First of all for ambassador if you haven't already, just go to the starting areas and do those. They're like 250-500 rep each quest. Easy mode.
Alright, AV. In AV when a player is killed you may removed their insignia. You get flesh/blood/armor scraps. These can be turned in for extra buffs/honor/upgrades/WINWIN.
Also, everytime you turn these in (Especially blood), you get reputation. Let's say, you have every reputation honored. It will give you +w/e for each reputation. Let's say you have 1 reputation at exalted. It will take the reputation you would normally get for it and split it among the rest of them.
When you are done with Horde/Alliance factions. It moves on to PvP rep and divides it among those. It's a lot faster to grind rep (Especially for Defilers) this way if you have an AV that drags on forever. If you are doing this it's reccomended you get a Frostwolf Insignia Rank 1 - Item - World of Warcraft So encase you are half way across the map and about to kill the boss. You may go back and turn in all your blood/flesh/etc. in for your rep.
Easy enough?
Kill stuff, loot, turn in. I've never gotten passed the PvP reputations. So idk if it scales down further.
Blood will give you the most reputation. I haven't done this reputation farm since beginning of wrath/BC. So it might be altered a little bit.
Let me know what you think.
Thanks,
