If you could convince people to actually go to OD1 then yeah, it would be better. But for right now, camping ant eggs GUARANTEES near-constant exp. Going to OD1 alone guarantees you nothing. >:
I'm rather sure that OD1 and OD2 aren't neat options, currently, because there's not enough people to keep the great spawn, and IMO OD1 is better than OD2 since OD1 has more aggro foes to draw than OD2. I got better results by making my Lif circle around me.
I don't like Ant Hells because I'd have to deal with, let's say, sharing spots. And I feel very awkward doing this. I don't even know if it's better mannered than OD multispotting.
Err... just a question, How much EXP/hour do your homuns make at Ant Eggs? Also, during Pre-renewal OD2 was popular because of the experience or spawn?
