me and my LS used to do eco quests once a week, nowadays we've stopped, but i've had the experience of doing all 3 ecos. from my experience, sanD is the easiest, winD would be next, and bastok is the hardest. If ur just doing eco's for fun, i would recommend doing sanD's. if ur doing the other eco's for fame i guess, you may want an escort guard. (if ur doing gusgen, you will want an escort guard for sure, ghoul's aoe drain is devastating to an alliance since they'll get full hp from a whole alliance) sorry to say i haven't done ecos in a while, but i hope this helps you out a bit. I also see a lot of ppl doing sanD ecos on sunday, just start shouting and you'll see that there's many ppl that'll join you.
