Someone linked to an interesting post last week about the perils of grinding Cenarion Rep that included the counterintuitive advice to not do the Cenarion quests right away.
My druid, first post-60 toon, just stepped into Zangarmarsh last night. Now, I'd like to tank end game with him, but frankly he's not guilded and is financing an army of alts who are leveling with various friends who got into the game recently. So I'd like to get him to 70 quickly and worry that skipping those Zangarmarsh quests for a while will gimp his leveling.
So my question to you vets is whether it's worth it for me to put off questing and just grind plant parts for a while, or whether earthwarden is a basically incremental thing that I can worry about once I've dinged 70, found a good guild and enjoyed epic flight form.
