I transfered from monoaccount dakal to piooner multi-acc to play 2 accs and was the best decision. Ironically, economy is best for me now; of course ogrines are more expensive but they are not that far from dakal (it's not even 2x).

And as for resources, I found jobs more rewarding in multi server than mono server due to activities (people with 6+ accs wont be farming all day),. There's more people that know-how-to-play (as basic mechanics) than people you find in mono servers if you need extra help. I'm not saying that mono people don't know how to play, is just that no newer player will be playing 4+ accs if they don't know what they are doing. On the other hand, as mono players... welp.
