I have been doing the missions at Esior's, because not many of my pets can do the ones at Saerielle. But I began wondering, are the lesser satchels there better than the ones at Esior's due to the higher level needed? (or any of the satchels really.)

It kind of depends on what you mean by "better." The sanctuaries green satchels are a little better than esior's green satchels, but esior's blue satchel's are better than the sanctuaries green ones.

I personally do only the 6 and 12 hour missions from both areas, because I like being able to send pets on missions and then not worry about them till tomorrow. While perhaps I would overall get a little more from only doing the sanctuaries missions, the difference isn't as huge as you'd think it would be considering the level difference. The time difference seems to play a much larger role in your rewards.

Really though, better depends on your play style. If you're online and want to send pets on missions every hour you should go to the sanctuary, if you want to send them on missions every few hours do esior's until you level up some more.

@Ash,

OK, yea I meant by level (so for orange ones Esiors<Saerielle, correct?). I might start doing what you are to help level up my pets a bit better soon. thanks!
