Becoming exalted with Sporeggar isn’t all that hard, or time consuming. Alot of the questing can be done as a group to speed the whole process up because the majority of the quests are based on killing mobs, rather than turning in a certain amount of loot.
There are a couple reasons you would want to be working towards exalted with Sporeggar:
1. You may want one of the pieces of gear (weapon or armor) that faction provides.
2. You may want the cool [Tiny Sporebat] pet for your pet achievement.
3. You may want the [Sporeggar Tabard] for your tabard achievement.
4. You are trying to become exalted with whoever you can
You start out with an Unfriendly reputation with Sporeggar but thats not a problem, you have 2 quests to help you get from Unfriendly to Neutral.
These quests have to be completed 4 times in total to get the a Neutral rating. You can complete these quests all the way up to Friendly however while you are doing these you should be collecting [Glowcap] for the quest  Glowcap Mushrooms. This is another repeatable quest and only has to be completed 4 times, meaning you will need to collect 40 mushrooms to get to Friendly once you have become Neutral.
Once you are friendly there are 2 ways you can go about this, if you run through The Underbog you can collect [Sanguine Hibiscus] and turn in 5 for the quest  Bring Me A Shrubbery!. This quest gives you 750 rep per turn-in so you can realistically do this quest 52 times (260 [Sanguine Hibiscus]) to become exalted. You can also buy these on the auction house because they are not Bind on Pickup
Or you can complete the quest  Now That We’re Friends… 52 times, which involves flying across the little lake (or walking around it) and killing 6x Bloodscale Enchantress and 12x Bloodscale Slavedriver.
This is the quickest way I have found to become exalted with Sporeggar, it only requires a couple hours of work, or some gold if you are purchasing items from the auction house. I hope this article was informative.
Until next time, keep fit and have fun!
