Minor exploit - Guild exp from multiple Tillers rep quests

I'm pretty darn sure this isn't intended, so here goes.

The farm rep dailies(shado pan etc_ you get after hitting tillers exalted, after planting the seeds you get a quest to clear.

Upon planting the seeds and clearing the quest (Rep Quest part 1) you gain guild xp.

You can abandon the quest, dig up the plants and do it once for each rep quest. ( so up to 60k x 5)
Could be worthwhile for leveling up alt guilds or something.

Nothing majorly gamebreaking, but figured it might be useful to someone.
